MTN . . . Zero stars might be too many

If I could give zero stars, I would . . . After using MTN as my service provider for more than 20 years and even recommending them to friends and family, I realized that I was probably just lucky that I never had to deal with this most ***********, misinformed, unorganized and ********** group in person before. Let me explain: I did not want to upgrade, but was 'harassed', two or three times a day telephonically, until I agreed to take the promotion. It was a package deal which included a device and another free device. Well, I am paying for both the devices now, going for 3 months. The contract (that I only received after asking several times) only states the one device. They refuse to give me a credit, only escalating the matter. They say they will send the invoices so that I can see, but never do. Managers, supervisors and/or team leaders are never available and the consultants are not authorized to decide on anything. I receive a reference number with every call, but it cannot be traced afterwards. I also get referred to MTN MyApp, but when I mention that, the consultant tells me that the app is not really working well. Sending an email does not help either, because other than the 'no-reply' email, saying that they will look into my query, nothing gets done. Oh and when I go to the MTN store, they say they don't have any access to the accounts. I am really so tired of feeling helpless and frustrated at the same time, tired of trying to be nice and tired of paying (already R1680) for something that was supposed to be for free. And on top of all of this, they moved my debit order date from the 1st of the month to the 16th - out of nowhere! I always make sure that there is enough money in my account for running debit orders, but not in the middle of the month! Needless to say, after my account was paid on 1 August, the debit order did not go through on 16 August. I received an email from MTN accounts department today that my service is stopped until I pay them. If I could give zero stars, I would . . .
