An impossible return

On the 1st December I returned a pair of toddler sneakers due to size in Midlands Mall Edgars Active, which I had bought in the same store on Thursday 26th November. I did not have a proof of purchase and therefore requested a gift card. The store Manager who said his name was Care was not willing to issue a gift card and insisted I do an exchange, which I could not as my son was not with me. We ended up going back and forth for a good 20 minutes and I ended up feeling like I'm treated as if I stole the shoes, as I was also requested to get a bank statement to prove this purchase. Thankfully I remembered to check my cellphone notifications and eventually solved the issue. As a manager myself, I really did not appreciated being treated like that. As a manager,store manager at that, Care should really fami****ize himself with the return policy. According to him gift cards are only issued for someone with proof. It's really not a good experience to buy something from a store and when you return or exchange it then you are treated like you stole it. I did not get any joy from Care and he displayed a rather unfriendly bad attitude in front of staff who are supposed to be guided by him
