simply dont care

i have sent at least 5 emails asking what i have purchased on my credit card that i have not used for 2 years and all i get told is yes you have used it i cannot carry on like this i get charged every month for purchases i have not made and when i ask what is it i purchased i get sent a statement but it just simply does not tell me for what it is for. simple fact is Standard Bank does not care even if a person is getting charged for something he or she knows nothing about. the fact is they just say pay and shut up. also please do not phone me you have got my email address you can reply with that i simply do not want to talk to another person that has no idea what they are doing if i dont have answers within 48 hours i will be forced to take this further
