Horrible service from the DSTV MULTICHOICE CALL CENTRE AGENTS

I phoned the call centre in February 2021 and was offered a promotion to continue paying R299.00 for the Compact package for another 3 months by their call centre agent. I paid as i was advised, and now on the the 20th March 21 when i called i was advised by Mbalenhle Dzanibe that it was not so & that my account is in arrears by the difference and they is nothing she can do except to refer to her manager to listen to call and investigate. To date i am still waiting for that manager to call me. DSTV IS A COMPANY OF ********* AND ONE ALWAYS RECEIVES HORRIBLE SERVICE FROM IT'S CALL CENTRE AGENT WHO ARE *****, *********** AND UNHELPFUL BUNCH. They only good to tell you to soft reboot and hard reboot, anything else it's too much for them to handle. It's not the first they make promises they can't handle. I hate this company
