Makro credit card *****

I am writing this email with great disappointment with your customer service regarding multiple calls i have made this afternoon when i recieved multiple sms notifications that my Makro Card is making multiple purchases at Pick n Pay and Foschini (Location unknown). The phone numbers called include: *** at 15:30 (6 minutes), 15:37 (9 minutes) where i was put on hold until the line got cut off; *** (9 minutes) also put on hold until the line got cut off and then again *** (11 minutes) where i spoke to a gentleman who eventually told me he has blocked the card and i should hold for the ***** department where i waited on hold again until the line got cut off. I then called right back again and asked for the direct lines of the ***** department which he gave as *** but these lines only ring unanswered.

I am not sure where else to call to report this ********** activity and to reverse the transactions that took place within 2 minutes of each other without so much as positive identification wherever the purchases were being made.

How does this ***** get investigated, purchases reversed and credit restored if the phone lines we are meant to call and report this ring unanswered?
