Trying to invoice more than what was agreed

I recently signed a two-year data contract with MTN the monthly pay able amount was R299.00 for which I am supposed to get 70Gb of data for the month. Account BA***.

I had an old contact that expired in February and I went to the local MTN store in Meyerton to ask them how much I owed to be able to close off the old contact so that it would not impact on the new contract. The lady looked up on the computer and told me I owed R359.01. I paid the amount at the end of January now thinking that that would be that and the new contract would be R299.00 at the end of February. Well low and behold I Get an invoice and statement for R470.20. I also get an additional 50Gb data that I did not request. On the statement it records that the extra charges are for Pro-rata data R83.87 and R65.00 which I also did not request.

It would seem to me that companies these days can just lump extra charges onto your accounts and just expect you to cough up. As I did not request this in my books this is *****ing, I am a pensioner and do not have the money to just cough up. Where are we going to in this country where companies like MTN who have an abundance of resources expect to squeeze the poor and needy dry of every cent they have. such greed should not be tolerated.

I phoned the call centre at MTN the lady would not listen to me and it became extremely frustrating. I asked that her superior phone me back she said that she can’t do that. Then I got really mad and suddenly, she said that she will get her boss to phone me back. Well, it is now a few days later and nothing has happened.

We are really going down a road of unprofessionalism in South Africa, I could expect it from small companies but not the big corporates. Can I not just pay the contracted amount of R299 without anything else that was not requested or agreed on?
