Not been charged internet on the credit card for about 4 months, just managed to finally log in to the billing account after emailing them because my previous login didn't work and find nothing there at all about credit cards or any payment details at all, just a printable bank Giro with the amount so far on it (almost £50 now).
Don't need to change anything they said, all your details will be carried over when the company changes it's name from Nildram to Opal they said, damn you Talk Talk, now I have to phone an 0800 number and find out what the hell has happened to being billed on the credit card every month.
