MTN Business - Not providing packages agreed to, still charging and not resolving querry - over 4 months!!!!!!

In June/ July of this year I started receiving numerous calls from call centres phoning on behalf of MTN. I was told that MTN was changing platforms and as a result the contract that I had for my various numbers was not available any longer. I received a number of conflicting calls with conflicting details. I then asked one the ladies that I was speaking to on the phone to e-mail me what my package cost and included - R249 this included SMS and airtime and 6.5 gigs of data. This email has been included in my digital communication / complaints (with the various reference numbers) The next month my numbers received only 1.5 gigs of data. I called MTN, provided all the security questions to be told that it is another company that concluded the deal and then I was put through to them where I had to answer the numerous security questions again. I did. I received a reference number, the next month there was no change, I called again and had to deal with 2 call centres once again, I received a reference number and nothing changed. I have repeatedly engaged both the MTN call centre and the MTN business call centre (called and e-mailed) and nothing changed. After yet another complaint I received an email from MTN saying that the package change was outsourced and that the company that this had ben outsourced would not deal with a third part and that I needed to call this company directly. I responded that I had not outsourced this part of their business MTN had and I expected MTN to resolve this. This response was completely ignored because the complaint had been closed. I have now called the outsource company Mobile Plus a few times. I have been told in the initial two complaint conversations that there was a problem between the capturing system (or what was captured) and the actual "package system", the interesting thing is that both times I was told that management was aware of this problem and had only recently found a way to resolve it - AND THAT THERE WAS NO PLAN TO PROACTIVELY CORRECT - ACTION IS ONLY TAKEN WHEN THE CLIENT CALLS. The only way to resolve the incorrect package is to request that the package is reversed to the old package , the call centre agent said he would submit the request (I wonder if the detail about the system being changed was a sale pitch lie). I asked to please receive feedback and confirmation that I was either going to receive a refund for the data that I had not received or once the package was fixed I would receive back dated data. Today I had to follow up with Mobile Plus who now have produced a service request to get the package fixed (all of a sudden, conveniently available while I was on phone). I was told that they would send it to me within 5 min of my call (still have not received this) and that I had to take this back to MTN to get it resolved because they can not deal with a third party. I am right back to where I started over 4 months ago. MTN will not take accountability but will take your money!!!! And I am still not receiving what was promised. I have asked to speak to complaints department to be told that the call centre deals with complaints. I have also asked for feedback from management and that has also not been received.
