Customer service dissatisfaction

I bought a shirt at Gateway on the 8th of October 2025. When I realized that it doesn’t match the outfit I wanted to use it for,I decided to return it, ever since I have never been able to return the shirt. The first time I tried they said according to the receipt it was a gift, but How as I bought for myself, I keep trying until I sent an email to H&M South Africa customer service the return email from Claudia in Johannesburg requested a copy of the receipt I did sent it as per their request. Everyday when I do a follow up I get a new ticket number since the beginning of the month today it’s the 19th of November and still counting nothing from H&M. I wonder they do the same as they are doing in Europe and in the US failing their customers like this!!!!! I am very disappointed with their conduct. They don’t deserve even a single star that should be half or nothing.
