MTN lost their credibility with me

MTN has billed my account up to 5 times the regular bill. I was helped in store twice without any results. Phoned them 7 times, was only helped after the 7th time and hung up on me twice. They had the wrong details, having updated them myself 3 times already! <br> I have received sms's saying my data is depleted when I have more than a GB left, been charged out of bundle rates, when I was using a large bundle.They keep on sending me sms's for my bill and it was going up a R1000 a month. Their communication, billing and service in this matter (for 3months now) has been very inconsistant and unreliable. I cannot trust any sms, email, or service over the phone, because the info is adding up, and my billing is not adding up either. I do not feel safe with them as a service provider and will encourage others to take their business somewhere else.<br> Everybody or company makes mistakes... it's just a problem when they are not owning up.
