SELLING A CELL PHONE WITH NO REPLACEMENT BATTERY AVAILABLE ANYWHERE !!!!

In January 2018 I bought a nice looking cell phone from PEP CELL at their Kenilworth Centre, Cape Town branch and it came with a 12 month warranty. From February 2019 the battery started to "collapse" meaning at 50% charge it switched off. Clearly the battery was failing. So I went back to buy a new one at PEP CELL but they do not stock batteries - AND NOR DOES ANYONE ELSE IN CAPE TOWN. I have hunted high and low but this model battery is not available. We all know that without a battery the cell phone is useless. I contacted PEP CELL and this was their response. "Good day Herman sorry for the inconvenient but we don’t stock loose batteries .Thank you MARY-ANN FERUS CELLULAR HELPDESK." Interestingly the type of cell phone I bought is no longer sold by PEP CELL. I REALLY FEEL LIKE I HAVE BEEN DUPED :-( There goes R800 down the drain. Thanks PEP CELL !!!! :-(
