Rude Manager

This afternoon, this same woman who has a bad attitude gave us hell. I bought a gate remote control and found the one I lost without having opened or programmed the one I bought from Kitwe. I took it back requesting for a refund or even a voucher. She started screaming that they do not refund. We kept on asking her not to shout as we were seeking clarity, that's when she called us stupid. I asked for a voucher or exchange for something else, she refused calling me stupid and must go back to school because I kept on asking questions. My sister and I became so angry and also started to shout. She is very rude, I agree with the previous complainant. I was looking online for the franchisor customer service number when I saw this complaint. She does not know what a customer is, it was a spectacle in front of the shop as we were shouting at each other. People like that are not supposed to work with people, I feel for her employees.
