Bad services

I called from last week to get an error code E143 fixed. Every one tried to help with no luck. I called an Installer and paid him R1950 to come and assist. After they left the DSTV went back to E143 I called them and was told they will see when they can come back as I am not there only customer. I called multichoice on the 8th Dec 2021. Spoke to Lechesa Moekena that told me he will call the Installer to come and repair the arrears. I have email him all the info. Yesterday I send him an email as no o e called me and till today he has not rep**** to me. He also told me if he can't get the installer to come and repair he will get another installer to come and help me. Still nothing this is very bad service
