No response after 2 months

Very poor service from mobicred over something that should be very simple to resolve. I was chared R178.14 x 3 on the same day at the same time for purchase at Pick and Pay Irene Farm Village Mall on the 28th of July which is 2 months ago. For 2 months i made numerous calls, emails and whatsapp messages without getting proper assistance. Ive been told the same story over and over and over and over but does not look like anyone at Mobicred cares about their customers. This is so bad and i am thinking about withholding payment on my account until they sort out my problem
