Multichoice bad service and substandard product dstv explorer 3A

We bought a dstv explorer 3Adecoder in November 2020, towards the end of January 2021 it started giving us problems with signal error messages. We took it back to Centurion Cell and TV where we bought and they advised us to take it to Aerial and Satellite Excellence in Waterglen which we did.

They exchanged the decoder with "refurbished" decoder which is possibly older than our 3 month old one. They told us that multichoice instructed them to exchange the decoders with refurbished ones after 2 months has lapsed.

We took this "refurbished" decoder, it worked for a few days and started giving the same error message. We took it back again to the Water Glen Aerial and Satellite excellence centre. At the beginning they tried to blame it on the installation until they tested it and realised that it had the same fault as the one we initially returned. They tried to exchange for a few refurbished ones which didn't upon testing until they got to one that actually connected.

A week later (today) the decoder is giving us the exact same problem..what is clear is that ALL these decodeds have the exact same fault and they keep exchanging them for the very same kind of faulty model. They kept on telling me to bu a new one, but the one we bought is about 3 months old. The 2 things I dont understand: 1. Multichoice sold us a faulty decoder, when we take it back to them they cant replace with new, they replace with another faulty decoder which is probably older than my decoder.

2. When we take the issue up with Aerial Satellite and excellence centre, they tell us to take the issue up with multichoice even though they are the one who keep giving us faulty decoders. There isn't even a guarantee that if we were to get a brand new decoder of the same model, it would work because they know that these decoders are faulty and should not be distributed.

3. I called their customer care, they also told me about buying a new one because clearly they themselves don't have confidence in the current model. They told me to go Randburg and I asked them to send me something in writing to take with me and they said the manager would contact me and I am still waiting.

The whole experience has been inconvenient, frustrating and unprofessional.
