Loyal customer receiving unacceptable service

I have been a loyal customer with MTN for a long period of time and have never recieved the such pathetic service like i have in the last 2 months!<br> <br> last month R600 worth of data was added to my account and the same for this month even though i buy 2 gigs of data every month.When i tried to resolve the issue i was faced with call centre agents who would rather put the phone down after they tell me to hold the line,not to mention the ridiculous 40 min wait to even speak to them.Even call centre managers raise their voices and start screaming at you.The following persons were instrumental in providing extremely bad service and promised feedback with none received: Liam who never escalated the problem and canceleld the call.carmen who put me onto her manager (lishiano) who made empty promises and could not assist me.Nthando Mabizela and her manager Fezile who werre to busy to assist a client and could not assit.Its been 2 months and nothing has been doen to assist me as the client in this manner.<br> <br> I will take this further as I am sure that the Consumer Protection Act should protect us against cases like this
