Covid Schmovid

I am very angry for the 2nd time now. I went to cClearwater to exchange something and they won't let me as I don't have the slip although I do have the swingtag. I don't know if they think there is another @****@ MRP. WHEN i left I was asked to show my slip repeatedly and I had to raise my voice eventually saying that I don't have it because I was trying for a refund or exchange and they would NOT HELP. I find it disgusting because other retailers allow you to return stuff even in Covid. They just quarantine it for a few days and then put it back out for sale and since we are talking chain stores, they usually have a lot of stock. The previous time was at Cresta and I was not allowed to leave the store, got into trouble for not showing or telling security on walking in and basically was accused of *****ing the stuff I was trying to return. They also went and checked all the cameras. I AM NO ***** AND I DO NOT APPRECIATE BEING TREATED LIKE ONE. It is DISGUSTING. iF YOU HAVE A SWING TAG YOU SHOULD BE ALLOWED TO RETURN/EXCHANGE EVEN IN COVID TIMES
