Cannot cancel stream packages -even after escalation

In Aug 2023 i reconnected my decoder at my new house. DSTV installer said i should change my lnb and cabling which was old i did. Then when it came to enabling the decoder had endless problems. Eventually bought a new decoder. This was now working mid Aug and it took more than a week to resolve. Once working i tried to cancel streaming service which i've had for years and Dstv self service and chat was not working. Tried to cancel through call centre told have to do it myself. Had to log an escalation on 21 Aug nothing happened again on 31 Aug as i see i will then be billed for 2 subs in 1 Sep. Checked again its still active on 4 sept. Now on hold for 30 min again and just got cut off. USELESS! My new decoder dish and cabling are not working error 108 and my stream supposed to be cancelledwhich is still on!! Ridiculous now i know why you're loosing subscribers. Please get back to me urgently
