BAD SERVICE

I am complaining for the second time because no one from MTN store even tried to help me with my problem. I logged my query on the 29th of September 2015 but even today my query its not being attended to because i havent even received any positive feed back from them. When I was doing a payment to my account I used a reference number that is no longer active with MTN, so they said the money doesnt reflect because of that.<br> <br> I was told to send the proof of payment to the collections department, I did and they told me that the query have been logged with the bank and ever since from then I havent been updated about this. MTN has a very bad service from the consultants to the management team. No one does follow ups on clients meaning they dont care about customers at all.<br> <br> I am so angry because now MTN wants to suspend my account because of this payment that is being delayed to be attended. I want the world to see how MTN treats their customers and they should change this behaviour because we are the one's paying their salaries. Can please someone tell me where can I get thier CEO or any share holders who can help me. This has gone to far I want to take action against them.
