Blocked card

I have been trying to use my card with game but been given problems with no solutions.The customer care claim to have called me but apparently "somebody else answered my phone and said they dont have an account with game".Now my account is blocked I cant use it when I try to call their customer care they are not answering their phones.Then I sent an email telling them my problem they respond by saying I should send a sms with my card number and I did now they are not responding.

This kind of customer care is very poor since the beginning of the week trying to get some help but till today I have not got any.Its very irritating because when you owe them they breath on your neck for payment but now that I need to use my card its a problem.Bafana Mtsweni.
