Bad bad bad service provider

I HAVE HAD ENOUGH NOW! My statement date was on the 5th. For some reason it was changed to the 11th in September and I was billed a second time for R950.80. Nobody can tell me why. Then I was refunded R720. Don’t understand this math. Now I keep on getting sms’s saying I owe R239.80 and my line will be suspended. Apparently MTN can change whatever they want due to some clause in the contract. They can change my statement date, my package etc……………... So much for TCF and integrity! I complained NUMEROUS times since September. Every time I am told it will be sorted out. But you keep on suspending my line. I pay my account religiously on 25/26 of every month since December when I changed employer. I requested my payment date to be changed to the 25th earlier this year. I am still waiting. Some of the reference numbers: *** – spoke to Albert – he did nothing. I phoned again, spoke to Ando – she opened my line and told me Albert did not do anything on my query. *** – spoke to Tsobeka – she loaded the query and apparently it needs to go to credit control or something. Phoned AGAIN today after receiving the same sms again and my phone does not work AGAIN just to get the same ******* story. Now I only get my data and minutes on the 12th, a week later than it used to be. I pay on the 25th every month but maybe I should just pay on the 12th as well. I don’t know what more I can do. I’m just a number in your system. I have been an MTN customer since cell phones came out. I received a phone in 1996 and then I could choose between MTN and Vodacom. I chose you. 24 years of loyalty means nothing to you clearly. I am definitely not renewing my contract with you. I am moving somewhere else and I am going to tell the whole world about your incompetency and ability to change whatever you want on my MTN contract.
