BT turning speed down and latency up ??

Question

BT turning speed down and latency up ??
Hi All & Happy new year
Wanted to see if anyone else has seen the same issues as I have.
Right 4 ISP's in the last 18 mths.
1. Zen internet - perfect but expensive, 7mb down speed.
2. Newcall (resold Tiscali ie TalkTalk) awful, ever degrading service, speed, latency and "locking/freezing" where had to reboot router to reinitialise connection to exchange.
3. Idnet - perfect, 7mb again, issues disappeared the moment I switched.
4. BT - same as TalkTalk - same old nightmare, and BT are not helping, denying any issues. (speed down to 3mb, latency v. high, rebooting router 3 to 5 times a day).
In the above sequence nothing changed in terms of hardware or line. Did testing with faceplate off - 3 different routers - all same results.
Changed to BT to save money, but it's been a bad move.
I can only conclude that TalkTalk and BT actually restrict access and speed. If a third party can deliver superior service on all BT kit something is seriously off - it does not seem likely to be accidental.
Any thoughts guys ?
(Currently trying to get contract canceled as service not fit for purpose, (click and wait 2 mins, or click and nothing happens, reboot router and it's ok again for a little while, but speed way down).
How do I get out of the contract and get back to a competent ISP ?
Any thoughts or contacts gratefully received.
(Apologies if broke any rules - first post).

Sorry to hear that your  having issues with your BT Retail services.
You will either be on the ADSLMax (upto 8mbps) service or if your exchange has been BTw 21cn upgraded you maybe on the ADSL2/2+ (upto 12/20mbps) service depending on your line quality and length.
However these upto speeds may not be the speeds you will get as ADSL broadband connections are very dependent on the distance from your property to the exchange and the quality of your line. The further away you are from your local exchange the slower your broadband speed will be.
To enable the community to help you please see the advice below:
Please see Keith's help guide here: Helping forum members to help you, it will go through some checks that are needed for us to help you.
A summary of the checks are:
1a) Is your router/Homehub connected by a BT NTE5 master socket, Adsl Filtered Master Socket or Extension Socket?   Please bear in mind that extension cables and extension sockets can reduce the broadband's performance. If you have an Old LJU master socket then please say.
1b) Have you tried the Test Socket? - if you have one. - Bear in mind that lots of manual distconnections/turning off the router/HomeHub will cause you more issues as the DLM will either reduce your sync rate, increase your noise margin or put you into a banded profile.
2) Can you please run a BT speed test (including IP Profile) http://speedtest.btwholesale.com (not beta version)[Best done with a wired, Ethernet, connection] After Quick Test is done you need to click "Further Diagnostics" to get IP Profile.
3) is there any noise on your line. dial 17070 option2 ,called quite line test, from landline phone. should be silent but slight hum normal on cordless phone.
4) please post adsl line statistics 
ADSL Line Statistic Help:
 If you have a BT Home Hub like the one below...
 Then:
 1) Go to http://192.168.1.254 or http://bthomehub.home
 2) click Settings
 3) Click Advanced Settings
 4) Click Broadband
 5) Click Connection or sometimes called ADSL (see picture Below)
The direct Address is http://bthomehub.home/index.cgi?active_page=9116 (for bthomehub3.A firmware ending in 1.3)
or http://bthomehub.home/index.cgi?active_page=9118 (for bthomehub3.A firmware ending in 94.1.11)
You will need to copy and past all the adsl line statistics ( Including HEC, CRC and FEC errors). You may need to click " More Details"
 If you have a HomeHub 4 then the majority of the ADSL Stats shown in the previous Hubs will not be there.
for HH4 users you can go to hub manager then select troubleshooting then logs and are look for 2 entries together which will show theconnection speed and noise margin for when your HH4 last sycned with the exchange.
There are more useful links on Keith's website here: If you have an ADSL connection, please select this link
Don't have a BT Homehub/Voyager?
• http://192.168.0.1 for a netgear router and look for ADSL adsl statistics with information like noise margin and line attenuation, connection speed
• http://192.168.2.1 for a belkin router and look for ADSL adsl statistics with information like noise margin and line attenuation, Data Rate
I'm no expert, so please correct me if I'm wrong
