Bad service

I received clothes as a gift from a friend, they were purchased at Canal Walk on the 05/11/2016. On Friday 11/03/2016 I went to Tygervalley because I wanted to exchange the size and I did not have a receipt since it was a gift. The manager refused to do the exchange, I even asked her if there is no way for them to check the purchase from their system, I can get the information they need by calling my friend while I was there, Manager said they cannot check on the system. They can only do an exchange with a receipt. This is bad service what if Ithe receipt is lost. Manager also said siomething about a gift receipt that is offered to customers. They do not offer that when make a purchase I know for a fact because i buy my daughter's clothes there and my friend confirmed that was not offered to her even though she told the cashier the clothes was a gift for a friend. Since Truworths took over I feel the service has declined drastically, they suppose to accommodate all customers. I am so dissapointed at the service, i do not see myself buying at Earthchild anymore.
