Bad customer service

I've purchased a decoder explora on the 4th of December 2021 on dstv online purchases. Never receive any confirmation of the purchase. Called Dstv and was told to go to the walkin branch. Went there they told me to call the call center. Called and was told to send the proof of payment. Called my bank to check which account was credited. Was told it went to pay@ which is a company that collects money for dstv. I called them they requested me to send them the proof of payment. I did that and I receive an email from them confirming the proof of payment and requesting Dstv help to allocate the payment. They told me to do a follow up with Dstv. Till today they have not resolve my quiry. Everytime I call I have to relay the story and keep on promising to call back.
