I have to say I'm impressed by how well Talk Talk handled my migration from Pipex.
I placed the order online, and was told that as TalkTalk take over the BT line then I wouldnt need a MAC code.
A week or so later I got the welcome pack giving a date when the line and broadband would change over.
This morning by the time I tried to use the phone it had migrated already and after I changed my router settings everything was working on the broadband side as well.
Sounds like a very familiar story i had six great months from talk talk and thought all the bad press they got was wrong then they went to do some routine work on the local exchange and then no or limited internet no or limited phone use and despite 2months of this and over 200 phone calls and 25 dead promises i still had to pay £80.00 to leave and it was worth every penny. i know what your thinking this wont happen to me .................just as i did
