Unknown transaction

oday I called about a transaction that happened on account that I didn't do myself. The agent I spoke to to went on to stop my card and said the matter would be investigated further . Now I have a huge problem on how this matter is going to be handled because for one the fault is not with me and secondly I now have to pay a further R70 for getting a new card while I wait 8 business days while capitec investigates. I called the complaints department and waited 21 minutes on the line to no avail and called customer call again to speak to someone and I was told a team leader would get back to me. I've been waiting 2 hours and yet no call back. I'm extremely unhappy at the moment and would like for someone to contact meas soon as possible before I take the matter further.
