Very Pathetic service from Multichoice

I changed my package to price lock last month, a day after I changed it , Multichoice send a technician with a new decoder to be installed, on the 22 May 2025 my docoders were not working, the error received is that must make payment, on 24 May I paid cash and they also debited my account on 26 May. On Monday 26 May 2025 I reported the error E48 To DSTV , they advised me that the is a signal problem a technician will call me to come and check it. Tuesday I followed up with them as the technichia didn't call me, they advised me that they did follow up with them and they will call me. Till today Friday the 30 May still waiting for the technician and my refund for the double payment. I paid double for the service I'm not getting. This is a pathetic service i have ever seen in my life😡🤬😡🤬
