Lying to customers, money making scheme

I contacted your centurion branch on Friday as the decoder continued to just erase all my pre recordings and scheduled recordings. I spoke to Portia and she said I should bring the decoder in as it is known for software issues. She explained that there will be no technicians needed as it is only a swop and not an upgrade. I would only need installation IF I upgrade to the new explorer. I took the decoder in today to have it replaced when I got home the decoder said “ no signal” I contacted your support center and spoke to Nomonde who told me to get a technician as they can’t assist. This was not what I was told by Portia. If I had to pay for a technician then I would have upgraded!! This is **************** and your business shows no value of integrity! Now I need to bring out a technician at a phenomenal cost because I was de*****ed by your ladies “assisting”. I have been having issues with the old decoder for how long and nobody ever said anything about software issues with that model. Why did you not do the right thing and recall the make and model???
