Useless RCS *****!

I went to purchase an appliance from Makro with my Makro account card. I have not used the card in over 12 months and do not owe any money on the account. I was told at the till that there were no funds available. It was then seen that R16000 was **********ly spent on my makro card in another province. All the transactions done at a Markhams store on the same day. I was then told to speak with the RCS representative in store. He instructed me to get an affidavit along with other documents. These were all submitted to him the following day and also emailed by myself to the correct email address. I have since then after numerous calls and emails to RCS received no feedback. I am still getting harassing rude calls from Makro to ask for payment! What the hell is going on RCS? And when will someone start doing their job? I need my money back! I believe the the ***** to be within the RCS by an employee. Disgrace and Anger
