CUT MY LINE FOR R170,56 when you owe me R1040-00?????????????????????

I have for the last year sent emails, spoken to EVERYONE including ER 24 for a funeral cover being added to my account when I upgraded my contract - WHICH I DID NOT ASK FOR. After sending complaints emails, explained this story over an over and over again we are no closer to having this sorted. I have Ishmail and Asentia in Life cover saying my query has been resolved yet I now receive my July statement and this funeral cover is STILL ON MY BILL. I have now refused to pay for this and requested a refund, and I am now told my line will be cut unless i log a dispute, so I ask the lady today on the phone at 14h58 please let have the number and put me though, AGAIN she puts me through to a department that HAS NOTHING TO DO WITH FUNERAL COVER and now there is no dispute logged and my line is being threatened and NO ONE AT VODACOM HAS A CLUE WHO FUNERAL DEPARTMENT IS!!!!!!!!!!!!!!!! If anything I am owed R1040 in payments for this funeral cover and they are threatening to cut my line for R170.56???????????????????
