Capitec internal *******

Good day

I've been having issues with money being deducted from my account for online purchases. I was advice to block the card and get a new one. I went into the branch a few times to be told it will take a bit longer as it's an international company. Then last week an amount of less than R50 was again deducted which i did not get notification. 2 days ago, and amount of R369 was deducted again. I went to the branch which they gave another new card and told the will contact me. Noone ever got back to me with the first issues. The consultant told me that the card disputes department said i should take it up with the merchant, how do i do that if i don't know the merchant. I feel that this is an internal issue as i get told to take a new card which imp charged for every time, yet the same issue accurses. How much does Capitec what to ***** from me before i get the assistance and my money?
