My contract fees went up 5 times

I have received notice about a charge from telkom mobile, as I do every time a charge goes through my account, and the fee was 513 rands as opposed to the expected 107 give and take a few cents.<br> <br> Ive called the customer service and was informed that since my contract expired the fees went up.<br> <br> I told the dude that i have expired contract in MTN as well and all contracts become month to month with the device fees falling off and from there on you only pay the remaining fees of the contract, in my case for a few months now it is R107 and small change.<br> <br> The guy insisted it is not the case here, so i told him he is lying to me and this is BS.<br> <br> He then told me that he will hang up if i persist talking like that.<br> <br> I have slurred at him and hung up, and will also go into one of the shops and make some noise there too<br> if they persist to ***** their clients like that.
