wow. what a strssful pain in the neck. hope you get loads of vouchers to try and make up for it.
i recently ordered a bag from littlewoods and when the bill arrived with giro slip i walked into bank to pay it off in full.
so, the next time a littlewoods bill arrived, i almost didn't even bother opening it because i knew i'd paid it. luckily something made me open it and to my shock, it said that i hadn't paid anything last month.
when i spoke to bank, at first they were saying, well if you'd paid, one of us would have been forty quid up at the end of the day last 9th november and that wasn't the case (so basically YOU must be imagining that you paid! i was so sure i'd paid though. eventually the tiller said he'd check what was paid to that referencce last month and he finally came back and said that a payment for same amount was made last month wihtout a reference!
so, it was totally the banks error. i told them to pay it properly and the guy still wouldn't do it immediately. he said he was going to try and get the forty back and then pay properly (with the reference).
all sorted out eventually, but very stressful as it was hard to get the bank to believe it could possibly be their mistake. They were so quick to label me another crazy broke customer fantasising that she's already paid this bill!
all very stressful
