No DStv but demanding money

Hi my name is Jurgens Pietersen. I have app**** for a DStv decoder on the 20th October 2021. Until today I have not received any decoder or any installation done at my property. I have contacted Dstv several times with no joy and a lot of empty promises. Yesterday on the 24th January 2022 I have received a phone call from a lawyer company demanding that I have to pay my DStv account which is in arrears. I couldn't believe this madness. I haven't received any decoder but they need a payment from me for something I have no joy of. On investigation I discover that I have now 3 accounts. Really!!! How can this be. I am very dissappointed in the service of DStv.
