Disgusting Service from ABSA

I have been an ABSA client for about 25 years and have twice now experienced appalling service in the past 6 months. I discovered ********** transactions made against my credit card over a three month period. I reported it at an ABSA branch and was directed to the card ***** division. On 3 occassions whilst speaking with the call centre agents, they dropped the phone on me in the presence of an ABSA Consultant that was assisting me at the branch. This was after me spending over two hours on the phone trying to explain the ***** to three different call centre agents. I was informed by the third agent that the second agent who was assisting me had taken a lunch break. This is whilst I was waiting on the call. I never received any callback or further assistance from any of the call centre agents or even the Supervisor. An email regarding the entire experience was sent to ABSA's Ops Manager and the call centre supervisor yet to date I have never received any call or response email. My account has been de*****ed of a substantial amount and charges associated with those ********** amounts are borne by me. I find it appalling that as a long standing valued Platinum account holder with ABSA that one gets to experience such service and to date I have not been refunded nor is the issue resolved. I find this service appalling and disgusting.
