MTN vsNASHUA MOBILE..MTN the worst ever.

I have read a few complaints regarding Nashua Mobile clients have moved to MTN their monthly billing has doubled or even tripled in some cases. I can attest to this. My average monthly bill for 2 cell phone contracts was about 2k per month. For the last two months my MTN bill has tripled. I would like to understand the difference between MTN charges and Nashua mobile charges. Phoning the MTN083808 or 808 numbers are like pulling your teeth with a pliers. Very painful. I have tried the numbers 8 times and 7 times I couldn't get through. When I asked to speak to a supervisor at 4.30 I was informed that they left for the day. I asked to speak to a manager, and was told the manager is somewhere, but not in her/hes office. <br> <br> I'm really disappointed with MTN'S service, its a JOKE. Think its time to change over to Vodacom or Cell C.
