********** purchase

On February 2018 there was a ********** purchase that was made on my Cape Union Mart account of almost R4000.00 and I was in possession of my card, I contacted RCS immediately after receiving an SMS notification thanking me about the purchase, they told me to go to the police station to make an affidavit stating that I did not make the purchase. I sent all the documents they needed and they promised to investigate the matter and revert back to me within 21 days which they never did, it is almost 2 months now after the incident. I sent them an e-mail asking for a response they never rep****.
