Bad service

On 21/05/2019 I bought a blanket at PEP Home in Soshanguve Crossing for R289, 99. The cashier checked the blanket for faults because same blankets are always being returned. To my surprise 2days later I found that the blanket is torn. I've lost the receipt, I went to the store to exchange it for something else, but the lady at the door told me they won't be able to assist me because I don't have the receipt. I explained to her that I don't want cash back, they can give me a voucher or I can swap it for something else, she still refused. So I asked if they would assist if I called their headoffice, she said yes. Headoffice didn't call me to tell me to go to the store and buy a blanket. And with the COVID-19 situation we are faced with, we still treated like we are stupid to even buy at the store!!!!
