Garnier product return

Hi

I bought 2 face wash and 2 face creams Garnier products Dischem Westgate. I have been using them for 3 weeks now,I have developed big ****les on my face.i returned them to the store they told me they can't take back since its Covid they don't return face product's.That information should be made aware to us upon buying.im very disappointed. I called the head office they contacted the store manager he/she told them they will not return them.What should I do with them???please help
