DStv multichoice

Good day, 26 January 2021 I phoned DStv in connection with Explora Ultra. I phoned them time and again and still the installer did not receive the decoder which should be installed 11Feb2021 then 19Feb 2021 and now today. So neither me or the installer didn't receive any coder or service. By the end of March 2021 they will deduct money from my account which I don't have any Explora Ultra yet. I talked several people at DStv call center and everytime it's a different story. Still wait for the manager to call me back as promised. Can you please assist me on this matter. Mrs M Jacobs ***
