Very Unhappy Customer

Good day I upgraded my contract in June/July and I took out the Vivo 25e over 24 months top-up with a premium of R499 a month. Since my first debit order, every month the premium is just getting higher and higher. I went into MTN at Southgate Mall where I took out the contract demanding some answers and absolutely no one could explain why my account was being debited more then R499

I am going to take this matter further because as we speak already my bill shows R501 and the month is not even done yet. Take a look at my profile and see how many years I have been a loyal customer and I am being ****** every month of my money

MTN is in breach of the 6 outcomes of the TCF act as I agreed to a curtain amount being deducted yet evey month I am paying more then I should. I want this matter handled and my premiums paid back for every month that MTN has been deducting more then they should. My installment should be R499 as agreed and not a single cent more

I am honestly so annoyed and very disappointed with MTN as I could have chosen any other service provider but I didn't and now I really wish I didn't do the upgrade
