Well, heres the story.
Other night i was signing up for O2 home broadband for my dad's office. I went through topcashback to get him £100 discount. I get to the final stage of the order, entering back accnt and debit info. At this point it decided either the info didnt match or it didn't like it. I dont have a clue why it didnt work..
Today i recieved an email from TCB regarding my cashback tracking, thats fine i thought as ive just bought a payg mobile. I check TCB and there is £100 also for broadband.
