Poor service

On the 4th of septhember i received an email saying imei violation and the services are suspended. I have been calling the call centre and no one was able to assist me. It is now the 18th and still have no access I have been calling the call centre at least daily still no assistance. The operators say dial *** i do not think they know that number almost does not exist as it says to dial 135 i have been using twitter and Facebook to get help but still no assistance I have been to the mtn store 3 times and they can not do anything but say call the contact centre It is difficult to be a customer and no one seems to care I was at the mtn store were i saw 2 other dissatisfied customers walk away. I ask to speak to someone in charge and the operator said need to send an email, i spoke to the consultants and asked to speak to the team leader the team leader refused to assist or even speak, during any time customer service was not a priority my kids need to use internet facilities as they approach the examination dates, i called the retention dept and they gladly gave me an amount to pay to cancel the contract all because they will not direct me to a person that can help iys a fri pm no call feom technical dept which was promised on Tues already all the twitter and facebook messages i sent out to them today have not been rep**** to Not very impressed
