Termination of account

I have recently upgraded my package to DSTV compact on the 15th of June based on the communication received from you. I took the offer on the basis that I will be paying R299 for the next three months as stated. On the 28th I paid my account which requested R111.93, later on the 1st I received a communication that I have to pay R303.60 i then opted to pay via the app which then requested me to pay R119.60. Unfortunately this was not the case my services were disconnected today due to non payment, now requesting R326.26 to be paid. I then called multichoice customer care to query, I was assisted by Terissa Jordaan and I was told that they can't assist me as I no longer qualify for offer of R299 as I did not pay for the upgrade within 24 hours whereas the communication from the WhatsApp when I did the upgrade started that the outstanding balance will be added to my next bill. I then requested for team leader, they said they are all in the boardroom and I have to wait.

This is totally unprofessional and ***********, can I get feedback on this complain. I feel I was lured to upgrade for your beneficial only.

I've attached the screenshot of the communication during the upgrade and my payments receipts.
