DISGUSTED BY DSTV MULTICHOICE

I'm having huge problems with MultiChoice and their service and are disgusted by the way they treat me as customer. My problem started the day I was given the wrong balance due on my account by the consultant. Firstly she gave me a wrong amount and then afterwards I had to pay again. I made two payments ending up paying more than what I had too. She said that it would be reversed. Never did it reversed back into my account. I got hold of the finance department. They asked me to supply all supporting docs.. Proof of payment.. I'd... Bank details etc.. That I did with pleasure but then the headache started. After numerous emails to and from them and supplying each time something different they requested I noticed they keep on saying something different and all sort of stories. They refuse to let me get in contact with management. I paid my account up to date with a smile but Im having real difficulty now getting my money out of them. Is there anyone that can assist me getting this letter to a relevant person so that my issue can be resolved. I really need my money back as it wasn't my fault at all.
