Pathetic Service MTN

I am very disappointed with the service i have received from MTN over the past 3 Months. i was given a call to upgrade my contract the lady explained that my package would be cheaper and the package has more DATA almost double , at the date it was meant to renew i recieved the same as i have the past few years so nothing has changed i made payment on my account for the outstanding amount and then gave a call to the customer care line , the lady i spoke to was the rudest most helpless person i have ever dealt with , after telling me she will reconnect my line but i must make sure i make full payment , i told her that the payment i made was for R720 and not the R710 required , i waited and my line was not reconnected i proceeded to ask her about the airtime and data on my package to this she rep**** i don't know what you get so i will give you another number that you must phone , when i got upset and asked why she could not reconnect the line before i email her the proof she told me that their clients le to them and payments are not made so she cant connect before she sees my proof of payment i then put the phone down , after a second call to the customer care number the second lady helped me in a few seconds and i was connected again MTN have really started going from bad to worse and now this, WHAT IS GOING ON MTN
