bad service

my order was cancelled by Amazon, after 5 days still no refund, after phoning them they had made a payment on the 5th day, and I now I still have to wait 5-10 working days, before I get my refund, and I have to take it up myself with the bank because according to then they did their job, very bad customer service, since they cancelled the order and not me, the refund should have been done on the same day, worse thing is that I still haven't received my refund after 10 days!!!!!
