Poor quality of service

I did a change of ownership for a decoder, then someone from multichoice called me on Friday to let me know that the change is done. I was not home at that time to check, when i got home it wasn't playing but my package is paid for on the 28th of August already. Saturday morning morning called the call centre spoke to someone who confirmed that the change is done, i just need to click on TV guide and select all channels then it should fine. I did that but still didn't work got an E30- 4 error. I called the second time but got cut off, and that person did not bother calling me back, how is that for customer service.Did the whatsapp service, the response said there's two decoders on my name and i needed to select the smart card number that is giving a problem, but i did not recognize both the numbers. So i called the call centre again on Monday the 14th September 2020, spoke to a guy who promised to have cleared the error, and told me to press TV guide, select all channels then click ok, then it should be fine. I told him that i did that on Saturday and he said it will work i cleared the error now, guess what i still cannot watch TV, it is still giving the error, switched off the decoder at the plug and switched it on again, not working. When i queried the smart card numbers that i got on whats up i was told they belong to I F Ndlovu, who happens to be my landlord, she's old with no whatsapp, so she once asked me to send a request on her behalf using my whatsapp to downgrade her package, then multichoice just decided to link my number to Ndlovu's account or details, it beats me why will they just decide to link a number to certain account without verifying with the account holder, i mean not all their customers will have whatsapp, i asked for that to be sorted but it is still not fixed. So it means i will not be able to use the whatspp service as my number is linked with and incorrect account, how stupid. Instead of Multichoice calling me to fix my problem, they are calling me to sell me an explora, who wants to pay more for ******* service. Multichoice needs to improve on customer service, cause their service sucks and they treat us like we are not paying for the service, take everyone in your company for customer service training.
