MTN ****MED ME

My account this month was almost double then the previous months. A lady phoned me about 3 months ago saying my contract is now on a month to month data package as it has been for a numerous time now. I told her she must leave it as is and when I need an upgrade I will go into the store for 1 as I don't do my upgrades over the phone. She said that it was fine. Did not tell me she is "upgrading me" . My phone was ****** 2 months ago so I went to the store and I wanted to upgrade 1 of my 3 contracts and was told that I have to pay R2500 for early upgrade. To my surprise of course as I was on a month to month data package. So I left it and just did a sim swap. I have cancelled my insurance with them as they do not pay out. But once again I paid for the insurance this month and for upgrading fees and pro rata rates etc. NONE OF THIS WAS EXPLAINED TO ME OVER THE PHONE. Went to store to day and they said phone 135... I've been with MTN for over 20 years and now they are ****ming me. I am livid. 135 doesn't even give me proper choices. I WANT MY MONEY BACK!!!
