I am a Talk Talk  customer. I applied to become a Talk Talk 3 customer mid May and was connected to Talk Talk the first week in June my only problem was getting my MAC code from my former provider. Talk Talk even sorted that problem for me and when I was having problems with my former provider Talk Talk even offered to stand by me. They are easy to talk to and  any problems you can't get over on the phones or help line Carphone Warehouse are always willing to help. I have had no problems with Talk Talk since I joined. But I am only speaking as I find them and I cannot say anything against them as beleive me there is worse out there than Talk Talk.
