Very poor DSTV Streaming App and customer service

I have been complaining about the current DSTV Streaming App version 3.0.0 which is the latest version available to me on My Samsung Smart TV since May this year with no satisfactory response from DSTV but they happily take my subscription every month. The current signal is so bad you cannot watch any of the channels related to the Olympic games. The channels buffer all the time and the picture quality is so bad that you can hardly see the people never mind the sport you are watching. The program freezes every 5 minutes and you have to reselect the channel to start again. My TV is a 2023 Smart TV from Samsung and i have today had all aspects of the TV checked by Samsung and there is no issues with the TV. we have even selected HD 1080 resolution but that makes no difference despite our TV being 4K compatible. I have sent umpteen e-mails to their help line and all you get is bouncing around from one step to the next. I have had my fibre line speed checked by both Samsung and my service provider and both say there is no problem but must be with the DSTV App. I have sent emails since 11th July complaining as there is no other method for Streaming clients without a decoder. I am told the matter has been escalated but how long does escalation take it is now the 29th of the month will they refund my payment? Phoning is useless as all they say the matter has been escalated. I Refer to my earlier complaint on Hello Peter in May complaining about the poor service. I receive done phone call which acknowledged my complaint but no action. Your DSTV Streaming app is not worth anything stop advertising it so that other people do not feel cheated Clearly DSTV is unable unwilling to respond and should be reported to Consumer Obudsman
