Pillar to post, with no resolution

I called in wanting to report a *****ulent transaction today, I first went through to Thato in the ***** department who then stated she couldn't see the transaction on her end and would need to put me through to online transactions department, when there i was told they could see it but it was apparently a card purchase (that I never authorized or purchased, didn't even have my card on me at the time) then the lady i spoke to said she can't assist i must be transferred back to the ***** line for them to investigate, was then put through to Sphamandla in the ***** department and he too said he needed to put me through to ANOTHER department and for whatever reason he's transfer took me to CCD Couriers... IMAGINE All of that later and still no reversal of the transaction and I dont have a case number or anything to follow up with
