Zara shocking service!

I had an awful and extremely disappointing experience at Zara Gateway on Sunday. I wanted to return garments that did not fit. I did not have a receipt but the tags were on the garments. I expected the standard response that a receipt was needed but responded that because of Christmas holiday chaos, I did not have it and how could we come to a compromise. Gift card or something. Just NO from Maud the cashier. I asked to speak the manager. Happiness came over and it got worse. She just repeated ad nauseum that no receipt, no exchange. I asked if she thought this was good customer service and she just said it’s store policy. I said that I have perfect garments that I can’t use but I could swap them with other garments that I could wear. She actually said that they will need to just live in my cupboard then. The best part is that instead of being irritated by the hold up, other customers in the queue were trying to suggest options on how they could help me. They were just as surprised as me at the complete refusal to even discuss options. I wonder how in this age of technology, a store such as Zara, is relying on a slip of paper? Seemingly not worried about customer service or brand?
