Horrible service and faulty merchandise

I purchased an Epson EH-TW710 projector last year September 2021, and this year in July 2022 the projector fan started acting up and shuts off after a few seconds. The lamp is still fine. The projector is still under warranty. When I took it back to Makro Strubensvalley (might I add, I stay in Potchefstroom 130km away) they had to book it in to Partserve because it was not eligible for an exchange or refund because it was more than 6 months since I purchased the device. I received one message with a reference number. When I try to find out the status of the repair (it’s been more than a week now) I get no feedback. I can’t contact Partserve directly because they can’t disclose anything about the device to me (the owner of the device). This is terrible retail etiquette and I want my money back for selling me faulty merchandise and not communicating with clients throughout the process.
