Online Shopping not secure with Capitec Bank

On the morning of 15 June 2020, the amount of R102.52 went through my bank for Amazon Video. I haven't got a glue for what that was, as I am the only one doing online shopping and I do not have an account with Amazon. I went to the bank the same day and 20 questions later they closed my card issued a new card for R70.00 They said that someone from Capitec Bank will phone me that same day to reverse this transaction and the costs will be R160.00 really now. I did not make that transaction, nobody from Capitec Bank phoned me either. My balances on online shopping will remain now zero as this issue is still not resolved.
