2nd hello peter complaint and still not resolved

I have been having endless problems with Multichoice, This is my 2nd complaint on Hellopeter. Last month i logged a complaint and Linda Magongo called me, she ensured me that she would assist me but i dont get any feedback from her, I sent her 3 emails which she doesn't even reply to, pathetic service . Multichoice messed up my billing, i paid by debit order and they didnt end up debiting, i **** manual payment on time but they still updated my credit report negatively, this has had a very bad impact on my credit record. I even spoke to a Supervisor by the name of Sello Mothoa that advised he will assist but still nothing, I have never experienced such pathetic service, it's like they just do not care. What do I have to do to get this sorted? again i am saying this is messing up my credit record and i want these records removed from the credit bureaus. I cant believe such a huge organisation can have so much *********** stuff. It's shocking.
