Extra Charges for 5 months no refund

Since December i have a content charge on my account above normal charges. I have the mtn router with a 3g sim card. i have to phone them every month to report this charge which is non refundable and ask them to cancel it and yet again they are trying to debit this amount. so now i had to cancel my service with mtn after years of being a loyal payer or else i will have to continue paying extra fees for something i did not sign up for. Nice MTN thanks for *****ing my money and treating your customers like this. Terrible service provider and i hope to never deal with them again. <br> <br> Funny that with these content charges they state that i activated it by texting a number but it is a modem / router not a handset so how the hell am i suppose to do this.<br> <br> These is no words that can describe how much i regret ever considering them as my service provider. I wish i rather stayed with vodacom.
