MTN UNACCEPTABLE SERVICE

On the 7th of May 2019 I received a call from MTN to offer me a better package with more data and services. I agreed to this and stated that as long as the services I make use of stay the same or improve. This is not the case, I can nolonger use the me2you transfer of airtime to my daughters. this function does not seem to be working. I lodged numerous calls and have reference numbers. I am told that the function is there yet I cant transfer from *136*3# or the MTN app. It states that I have a 0 balance. Now you would think that after 3 escalations and me requesting to go back to my old contract this would have been sorted out in a day or so I have have been busy with this since 25 June 2019, MTN please respond, this is the latest ref ***
