make sure the letter is sent recorded delivery , and keep a record of any telephone calls and correspondence you have between your self and TalkTalk .
I have been here for many years and have seen many people with connection problems , with the help of other forum users , we have been able to self diagnose there problems and get repairs sanctioned much quicker , sometimes by the ISP , as in you know where the problem is or by the Op them self , as in house wiring or simple changing the WiFi channel .
I cant promise a fix every time but the success rate is IMHO very high and much higher than some ISP customer support teams to include TalkTalk .
What is strange about your case , is you have said you have moved and the problem moved with you , which to me says you moved the problem with you , which says to me the problem is your side of the telephone socket .
