Surely this is wrong. ( Unable to get ADSL and Mobile broadband SUPER expensive and doesn't work)

Question

$115/month for wireless broadband ( that works 5-10% of the time) for ONLY 15GB a month is the price?? Surely this is wrong.
There is no justification for a price so large for so little data for a service that barely works. Apparently we can't get ADSL because of A: no ports and B: pair gains line to the house. ( Both of which i've seen no proof of) Why is this a problem now when 5 years ago it wouldnt have been??? I've lived 40km's out of town and had perfectly fine internet connection, now I live 4 minutes out of town and can't get it. I must not have been put onto the correct technical support or the people I'm talking to don't know what they're doing. 
Because it barely works now I have to use my phone, which adds a huge amount to my phone bill because phones only have 2-4gb of data. There's no other way of putting it other than we are being robbed in broad daylight. This is now the 3rd month I've been negotiating with Telstra about these charges. 
So who do I talk to to either get an ADSL connection and surely this price is wrong or just hasn't been updated? $115 for 15gb, everyone I've talked to has laughed and thought I was joking.
Have tried negotiating with Telstra for months now, as I said must be getting the wrong people. Have called the Ombudsman and was put onto someone who just spent a longer time telling me we can't have ADSL. 
There is absolutely no justification for the price and for not being able to have ADSL.

Hi mate  First of all, it sucks but telstra is not robbing you or doing anything wrong. When they say there is no "ports" they are correct, and it means there are physically no "spots" or "connection points" left at your local telephone exchange to connect an ADSL service or for that matter even just a "normal" landline connection. When the exchange was built no one could have predicted the massive future demand for internet. There are so many more houses, units, sub divisions etc then was forseen by ANYONE, not just telstra, combined with an insane increase in the amount of data demanded by each service. You asked about being put on a "pair gain" system. It's basically just a way of running multiple services down the one line- technical name is multiplexing. They invested in that technology so you would at least have a voice service, but as the line is already being used for more than originally designed for there's no way it could support a fast internet connection also. As for your location, when you were further out of town there would have been far less demand for ports, now you live in a city where the demand is much much higher. Disregarding that, it's often just a lottery whether you end up in a suburb with spare ports or not. Now look, telstra is a private company with shareholders to answer to, so why would they do anything which is not profitable in the end? They owe you nothing!! In fact my family and thousands of other aussies own telstra shares and i cant say i'd be happy if they were flushing our money away. These days internet is almost an essential utility which is why the PUBLIC sector is building the NBN. So if everyone will have that soon and copper will be redundant, why would telstra continue upgrading the old network in the meantime just to lose every dollar they spend? It does really suck but there's entire suburbs which can't get ADSL for the reason that they were built after the NBN was announed. As for mobile broadband, yes it's expensive. It's also quite expensive for telstra to provide it and their mobile towers are very limited in their total data output. This is why you pay far more for less. The more data people are downloading the less calls the tower can take. A single phone tower can often only support labout 200 calls simultanously., with some bigger towers with multiple carriers supporting around 1000. a single fast ADSL2 connection can get 20mbps peaks, well that 1000 call tower could only take about 12 x 20mbps internet downloads before it's maxxed out- thats with zero calls. Now think about how many people have mobile phones these days and what a critical service it is. The result is that carriers have to put a low cap the 3g/4g data allowances and aggressively price home wifi broadband Because the number of phone calls is highly variable and being the higher priority service, your internet speed will always depend on the number of calls being made. The tower will always drop your internet to bare minimum to try and connect every phone call if possible. In a way telstra, optus etc are just maximising their investments by selling off their "spare" 3g/4g tower bandwidth, it's super expensive but it's your choice too. They spent the money building the network so it's their reward for doing so.  All you can really do sorry apart from moving is go on a waiting list for a spare port and wait for the NBN. The NBN will probably come before a spare port sorry!
