Cancel my account

I've requested Makro/RCS to cancel my credit card account on numerous occasions since September 2015, but my account is still open. I went to the store in Ottery and spoke to someone over the phone and they told me it would take 3 weeks. Since then I've emailed cancellations and was asked for my ID number which was sent (as well as a copy of my ID) but no further response. This email process has taken place twice... they ask for my ID and then they don't respond after receiving it. Why's it so difficult to close the account? I don't owe you anything, instead there's a R212 that's owed to me but because it's such a mission to close the account (I need to send proof of cash payment even though it's on your system) I requested the account be closed without paying me back that money. <br> <br> I just want my credit card account closed immediately.
