Intermittent Line Fault in windy and wet weather

Question

Hello,
I have been experiencing an intermittent fault with my phone line since getting BT Broadband in November 2013, which at first I believed to be a broadband issue. It started with the home hub disconnecting, flashing orange and then reconnecting.  After a few more weeks and performing tests through the test socket with various different ADSL plugs I noticed that the fault was happening when the weather was poor outside (wet/windy). We were sent out a Broadband Engineer who could not find the fault, he changed the faceplate of the Master Socket to a MK2 who said it would stop interference from the weather.
A couple of days later the weather was bad again and the fault continued to happen every time the weather was windy. For another month or so over Christmas and January we put up with the issue as the threat of the £130 call out charge is too much for us, my girlfriend and I are mature students so we can't afford that if our fault doesn't show when an engineer turns up.
I have been performing Quiet Line Tests through the test socket when the issue is happening and have experienced noise, popping and even multiple disconnections on the line. This week I finally got annoyed enough to book an engineer  and reported a Line Fault and miraculously managed to get one for the next morning (Thursday 6/2/14).
The engineer turned up and I explained the Intermittent fault to him and the noisy line affected by the weather but of course the weather that day was fairly calm. He performed his tests and said he couldn't find any fault and mentioned something about High Resistance?. He was nice enough to call up another engineer with a bucket crane so he could look at the telegraph pole. He told me he found that a joint up there snapped off in his hand and was probably the cause so they replaced it. They also found another piece of equipment on the exterior line (it looks like a black plastic sausage?) that was full of water so he emptied it and closed it up again.
For the first 23 hours the connection had held since the visit but then started disconnecting again and I'm experiencing the same issues as before with the current bad weather we are having even if it is only slightly windy.
So I am at a loss of what to do now. As the last engineer did all the tests as well as check the cable from the pole to the master socket I feel like I will be stuck with this issue for as long as I stay at this property. I cant afford the call out charge if the next engineer finds no fault. My personal opinion is that the line from Master Socket to the pole needs replacing as its possibly getting wet and or is corroded and the rain and wind make it worse but of course I’m no expert.
I should also mention that when the weather is clear outside the phone line and broadband works absolutely fine.
My setup is a BT Home Hub 4 (Type A)  and a phone which are both connected straight to the MK2 Master Socket which is located under our window (It is the only Master Socket in the property). On the exterior of the building the phone line goes up to the roof and along the side and out to the telegraph pole which is probably no more than 10 metres away.
Here is the noise margin and bandwidth results after a disconnection yesterday :
13:25:26, 08 Feb.
(81555.380000) DSL noise margin: 5.90 dB upstream, 6.00 dB downstream
13:25:25, 08 Feb.
(81554.270000) DSL line rate: 1147 Kbps upstream, 18456 Kbps downstream
13:25:13, 08 Feb.
(81541.820000) CWMP: session closed due to error: Could not resolve host
Bandwidth:
1163 / 16568
I'm not sure if these are the stats that are needed so please advise.
Any help and advice would be greatly appreciated.
Thanks

I've had very similar in the past, from what I remember it took maybe 5 engineer visists. Each one plugged the test kit into the master socket, scratched his head, went to the exchange, came back & scratched his head a little more.
The last one that turned up happened to arrive on a fairly bad day weather wise - that's when he noticed that the pole must have been hit by lightening at some point, and had burnt the wiring on the inside of the hollow pole we had. Burnt wiring inside the pole while it's being blown around by the wind was causing a short.
Was a 20min ish job to run a new line from the pole to the house & then it was all sorted permanently.
Your issue may be different, but it really is a matter of getting feet on the ground while the fault is happening unfortunately.
