DSTV INEFFICIENCIES

I have been subscribing to DSTV for over 3 years and just last week they send me a statement to say that I have 3 decoders. I only have 2 decoders. My account Number is with DSTV is ***8. I have been paying my account for the past years without any defaults. On the 4th of July I called DSTV and spoke to Nikita Ref Number: ***8-C1 who said was going to investigate. Today on 9 July 2019 my DSTV services was discontinued reason being I owe them for the 3rd decorder which I dont own. They said they cant tell in their system how that other decoder came to be added to my account. I called Usesethu complaining since I dont own 3 decoders but said she will investgate Ref No: - ***8-C2. I then called an hour later and spoke to Diego ***-C3 who now said I should pay R160 to be reconnected but why should I pay for a decoder which I do not know how it came to be added on my account. They also said they cant find a record of me requesting for the 3rd decoder. Iam so frustrated now have to pay R160 for their mistakes to be reconnected. My Name is Leonard Mafunga, My Account Number with DSTV is ***8 and my cell number is ***. Whay should I pay for their inefficiencies.
