DSTV accusing me of ***** on my account

I'm livid right now with DSTV to a point where if I could go to their billing department I would. On the 6th of October I had paid my DSTV subscription an amount of R739 as per checkers print out. I had recently installed an explorer with a second Xtra view. My extra things on explora were not active I had to pay and extra R295 which I paid. Everything was fine until the 13th October my services were cut off showing error code E16-4. I called customer care and was told my account was blocked because of a ***** investigation on my account which I did not understand and how one *****s DSTV services. I called again the 14th spoke to Amy who said she will clear the error which she said she did because I was calling from work, when I got home now all my decoders were off whereas it was only one that had a problem. Called again to be told I need to go to Multichoice because they can't help me over the phone, I go to Multichoice to be told I didn't pay for my premium package for December which came as a surprise to me because once you don't pay you get disconnected and I knew I had paid December. The gentleman who was assisting me at Adel center DSTV of the name Manquin or something like that was very rude banging the table and shouting that I did ***** on my account basically calling me a *********, because of some lady who did ***** with customers around Port Elizabeth who was working in Newton Park whom I don't have a clue who that is. I than left looked through my statements and found payment for December went back assisted by another gentleman didn't get his name unfortunately, he looked at my account now he says he sees I paid in December but in January I only paid R337 and for February I didn't pay. I confirm with him yes I paid in Jan they amount, February I didn't pay because my services were off. I than ask him since when does DSTV leave your services on when you didn't pay he couldn't answer me. We move to March month I ask him if he can see the payment he says yes and than I ask now how is my account in arrears he couldn't answer. March I had to pay twice R680 and R459 because I was told my account is in arrears. Nobody could help me now I'm told to reconnect my services I need to pay R1600 now I want to know the money I paid this month what happened to it and where did it go because they say in advance when you pay. The numbers they gave me for the billing department nobody works there because no one answers the phone
