Goodwill Industries complaint: Refund

I purchased some clothes on 3-8-23 they had no dressing room to try anything on so I ask clerk if any of this does not fit can I bring it back she said as long as you have your receipt and the little color tags was still on items so today 3-9-23 I took the items that did not fit back in same bag with little colored tag still attached even the same bag I was given they told me I could not get a refund I ask why the manager says oh you can only find something else I explained that was not told to me upon purchase. If the policy is no cash refund it should of been stated to me but it was not I assure you the lady that rang me up was standing in front of me and the manager when I told the manager what was and was not told to me the cashier did not deny what I stated she originally said I left with clothes that I brought back and my receipt please help me this was in no way neglagenc on my part. I just wanted my money back for items that did not fit as I took a picture of the receipt I noticed that she had not circled all the items I was returning.
