GSRDropshipping

This is the worst company I've ever encountered. They used the worst supplier, and as a result, several customers not only complained about the poor product quality but also received damaged or even used goods. I was furious and had to refund them.
I contacted customer service, explaining how bad the product quality was, but they demanded I upload pictures of all the damaged items. The problem is, I had already refunded the customers, and I was already very upset. When I contacted customer service again, they said they couldn't issue a refund because I had only submitted partial pictures.
Their attitude was indifferent, as if they didn't care at all. This is truly the most unprofessional and infuriating app service I've ever encountered.
