Worst service ever

I was with Nashua mobile for over 6 years, and I received great service from them, I paid my account EFT on the 1st of every month, received my statement via e-mail on time, could get through to their call center within 5min, either to block a ****** cellphone, adjust limits, or receive itemized billing, they always had my query sorted immediately or before the end of the day I called. I was a very happy customer.<br> Now I have been forced to move to MTN, every single month there's a problem!<br> I have wasted no jokes, about 5 hours in the past 6 months sitting on hold with MTN. Problems ranging from:<br> 1. One SIM card just magically unRICAed itself- how on earth is that possible? So I had to buy a new SIM- this has happened twice<br> 2. My invoice delivery system automatically changes from e-mail to post- I never requested this change<br> 3. I pay according to my account number(for 2 cellphones) the whole payment gets allocated to 1 number and the other is soft-blocked for non-payment<br> 4. Then now I get charged over R700 for pocket switch data calls- MTN says I went over my data usage. How can someone who uses an average of about 300mb a month suddenly use over 5G???<br> BAD BAD SERVICE!!!!
