COMPLAINT: BATTERY WARRANTY NOT HONORED

I have purchased a battery at Sasolburg Battery Centre in March 2022. The battery died after 23 months and still under two year warranty. When returning to the place where I've bought it, I was told they do not sell that brand of batteries (ENERTEC) and they refuse to cover warranty over it or replace my battery. However I proved that I bought it at their store since it was engraved by them (SBC 30/03/2022). I also provided a proof payment via my bank statement. The franchisee (Teboho Mokebe) understood my claim and forwarded my claim to BATTERY CENTRE head office. My claim was handled by Philisile *** / ***) at the head office who stated that I had no claim since I bought a brand in their branch, which is not their brand. I further wrote an e-mail to Philisile and followed up with a phone call to her to ensure she got my mail. She confirmed receipt of my mail promised a response in writing to no avail.
