Capitec Has Bad Service

Today I wanted to pay my school fees which cost R850 and my available balance was R893.41 but when I went to withdraw it, I found out that it has been deducted to R786.11 .I decided to make a Bank Statement and I discovered that Showmax Ranburg has deducted R99 from my account. I don't know how because my online limit was R1. Showmax Randburg wasn't suppose to be able to deduct money from my account if my online limit is R1. When I reported the issue to Capitec, they told me to pay money in order for them to carry out an investigation on how my card has been comprised. Capitec wanted me to pay money for the investigation of each transaction that took place without my knowledge. My card has been comprised, I'm loosing money because clearly it is not safe with Capitec and Capitec is telling me to pay more money in order for them to help me find a solution to my problem. A problem that is not even my fault because Capitec failed to keep my money safe. Capitec has bad service and us the clients suffer because of their bad service.
