PATHETIC CUSTOMER SERVICE!

So I took R269 wifi package with mtn, paid pro rata and month in advance amount totalling R433. I then was debited again for the very same R433 which I reversed. I also sent an email complaint that went on for days and days and was never actually resolved. Ended up calling in and was told that the matter will be escalated; never happened. Month end comes and instead of being billed R269 I am now billed R919, for what I don't know!!!! I go instore because you can never reach anyone on their billing number. I am told by the agent that the matter will be escalated after I have to physically leave the store in order to go to the bank to get a bank statement showing the amount of R433 that was taken from my account, which I am told they have no record of. I am told that they will resolve the matter after a day and I must just wait for a response. No such thing happens, instead I am sent threatening messages a "day later" telling me that I must pay R919 or they will disconnect my wifi by the next day. I call in to the billing department and am on the line for almost 40 minutes, holding and then after speaking to the agent told that she is putting me on hold and then she cuts the call after putting me on hold for 15 to 20 minutes! I don't get any joy by calling in to the Kokstad store where I initially went in, they don't answer on the first ring and then when they do answer the lady who took the call was extremely rude and abrupt and tells me she will have to get someone else to call me back to assist me; this also never happened. I call in to the gateway branch, they also do not answer on the first ring and I am told by the person on the other side of the line that since I ordered online, they cannot assist me, he instead wants to give me the email address which you never ever get a response from. So all in all you basically get given the runaround, no answers, no customer service and no accountability or record of any payments that you made. I was also told by the agent who put me on hold for 20 minutes and then cut the call, that the billing department is requesting my bank statement, which I have ALREADY submitted at the Kokstad branch, so when does this nightmare end???!!!!Don't waste your time with MTN!!!!They give the WORST MOST PATHETIC SERVICE EVER!!!! They deserve ZERO stars!!!!
