Hmmmm, I had a similar (but much more extreme) issue at the end of June which caused my bank to suspend my card - much to the inconvenience to me as I discovered as such when (trying) to pay for a shop in Sainsbury's!
I then phoned my bank to find out why and they then told me my pending payements to my bank account (of a blance over £1000) took me to -£1200, well over my overdraft. When asked what this was the woman from my bank just gasped and said "oh God!" - Game had charged me £14.99 over 200 times for a Ganondorf amiibo!!! They were charging every 15 to 45 minutes for 2 days prior. Of course I kept the card suspended as those charges were still occuring. They managed to fit 2 in whilst I was on the phone (luckily the bank was declining them). After speaking with Game they finally succeeded in stopping trying to take payments after another 2 days.
My money was never taken by Game, but kept in a suspended state until it was overdue being claimed 5 working days later.
In order to pay my rent, I was advised to claim for an extension of my overdraft from £500 to £1500 and had to borrow £1000 (my rent) from a family member. I was livid and stressed for days.
Happily though, they gave me the amiibo for free and all my money back...
After more complaining, by me stating that was not satisfactory, they eventually (two weeks later, so not actually that much time) phoned for my bank details (the cheek I thought) so they could transfer £250 compensation into my account.
Still haven't spent any money with them since and doubt I will again - well that is my plan, but I sense them having an exclusive bundle/collector's edition offer on something in the future that I won't be able to resist!
