Upgrade complaint

Good day,i would like to lodge a complaint I recently asked for an upgrade in November 2022 and it was never actioned,i called in and it was lying on the system as a quote.I called in to activate for the 1st December,but it was activated immediately.I was gthen been charged for my old contract and the new contract simultaneously and was charged prorate for December as well.I called in again and had upgrade reversed,which was done.I was credited for R569.00 but not for the prorate of R580.63.If you look into my account you will see the tickets logged for correction and to date has not been resolved.I am a long standing client and am extreemly unhappy with what has transpired.You can contact me on ***
