DSTV Multichoice , Managers and staff members Poor service and like fraught Behavior

Last year 2020/12/04 have app**** for a price log that come with an explorer decoder , it wasn't delivered and I told them to cancel the account , they said they did , only to find out it was never canceled and the very same account have affected my credit score as the creditors say I have a Multichoice decoder payment plan account which was never paid since its existence ????, when I'm seeking assistance on this regard , multichoice staff members just put my call on hold for the hole day and ignores me , and this has been happening since last year and all want from them is to cancel this account , as now they want me to pay for goods and services they never provided me with. This is not on and If there is anyone out there who can assist please contact me on this email *** or on this number *** . I even tried to contact them today and I got the same treatment I even asked for the manager or supervisor on duty but no luck and the staff members who never assisted me today is ( Rudolph Sekolane and Nqobile Zungu ) Rudolph said he will send my query to cancelation via email then Copy me as I gave him my email then he made me wait and never come back to me and Nqobile did that as well , she said she will transfer me to the cancelation department but she did not as she kept me on hold for 3hours can you believe that
