Shirt Return

I am so annoyed with your ackermans eerste river staff, I purchased a shirt for my son and its to small I lost the receipt however the swing tag is still attached.They refused to take it back nothing was wrong with shirt just small and says 4-5 , you know what infurates me more is cape town ackermans and kenilworth left those black tag things in and the managers just disregarded me, is this how u treat your loyal customers seriously. What is going on in yours stores a party that I had to attended had black metal tag in on day I had go to into your store and have you remove it. Your customer service sucks really and again petrol I drove out and your managers lack people s****s and customer service first my son lion guard pjs,my white dress and now this refusal to take the thing back and it hadn't even been worn
