Hmmm I wonder if it hadn't been noticed he hadn't been making the payments (through no fault of his own I stress...probably) and he continued to watch them scot free he'd complain?
One of two thinks have been done me thinks. 1- bank statements were NOT checked. OP had no idea if payments being made and that some illegal fraudster posing as a rich Nigerian diplomat has in fact been pinching out of his account for ages.
2- Bank statement HAS BEEN checked and, what, they're not taking the money? Ah well I'll keep that stoom. Maybe no one will notice. Chance it me thinks. If they eventually bill me I'll pay it of course, but its their job, no mine.
I make a point of checking my statements. I wanna know Im paying my DDs etc so Im not given a shock 5 months down the line.
Mind you It doesn't stop the bank phoning up and checking what you've been spending your money on and it is in fact you thats been spending it. "?55 in pub" Yep me. "62.75" in club (same night, cash back included) yep, me again
... and then getting told your card has been comprimised and would be cancelled anyway as it had been used in a place where known fraud had taken place. Then when i ask "Any chance you could tell me where this was, so i dont use it there again?" "sorry we cant give out that information, computer says naw!"
So in the end whilst the bank/DD company or club maybe should have got in contact earlier (if they didn't) OP should have been checking his statements and making sure, if he wants to be sure events like this didnt arise.
