Miladys canal walk poor service

I have never been treated as badly by anyone as I was treated today by miladys canal walk Manger and staff. I come to return 3 items which didn't fit. I never had a receipt cause I returned a previous item on the same receipt 4 days prior, the cashier gave me another receipt but not my original one back as she needed it. When I come to return my goods the manager told me they could not refund me cause I don't have the receipt. She told me they would give me a voucher which I didn't want,I explained as best as I could that the lady who assisted me 4 days prior kept my receipt. The manager and the cashier spoke and looked at me as if I was something that crawled out of some dirty hole. I just wanted to get the hell out of there therefore I took the voucher. I will never ever again put my foot in miladys canal walk again. Disgusting poor service
