MTN:worst mobile & customer service provider in SA

For the past twenty minutes I have been trying to get through the MTN call centre, and my call has been dropped over 10 times in 30 minutes. I am unable to understand how such an company can be so unprofessional and have substandard work ethic that calls can be dropped.I have been unfortunate to be stuck with this horrible service, and recently my phone got ****** and I could not get any assistance from the Claremont Store and had to call the centre where my call was dropped 5 times up until i got some help. I do not understand why customer service is so difficult and I am sick and tired of MTN's service and I just want to cancel my contract because of their appalling service and they can't even get that right.
