Selling Lies/ Inconvenient truth

I was cold called by an Absa agent “do you want to upgrade from Gold to Premium banking? It will only cost you slightly more than what you are paying R169 pm including the credit card??” So we worked through what I was currently paying for a current account and credit card and the upgraded banking would only cost R15 more. On the recorded telephone call I accepted and then realized when I got the monthly statement that the credit card fee was not included and I was effectively now paying double for the same terrible Absa service. I have complained directly to them - they have “escalated” “investigated with IT “ and tried to trace the recorded call from the sales agent which they are conveniently now unable to recall. Weeks have now passed and they have seemingly just ignored this issue and have offered no solution. This is blatant deception by a large South African corporate and needs to be resolved ASAP. Any one out there steer well clear of Absa and their dirty tricks.
