Family Dollar complaint: Disrespectfully treated customer

A couple weeks ago I bought Milky way bars , I don’t buy anything made in Canada, I didn’t realize until I got home that milky way bars are listed as made in Canada,I took them back to the store and said I wanted to return them the worker held them up and yelled and I do mean yelled you can’t return food! ! I said why not, they haven’t been opened, I don’t buy anything made it Canada, I simply want to swap them out for good old made in America Hershey bars she seemed to have to think about it for awhile, I assured her just a swap out.she agreed to that but I had also decided to do some more shopping while there, when I was going down one isle she was coming up the other and questioned me me if was going to shop? As inferring I was supposed to make the swap and leave, I assured her that I would make the swap when I was done shopping, there was also a male attendant working at the cash register at this incident, I was under the impression that a store is a place were the customer comes first and that a worker should encourage them to shop at the store NOT try to belittle them by falsely saying that they couldn’t return food doing so loudly in an attention seeking way , she also enterupted me while I was talking to her and asked for my phone number, for the refund she then made a fool of herself by putting in information wrong and had to ask for the number again. Unfortunately I ride a bike for transportation the Dollar general is about a mile so instead of changing patronage I returned and about two or so days ago I was in line ,Chris the manager and a worker just standing there doing nothing while Chris marked with a gun reduce price I asked Chris the price of the chips Ahoy cookies , she said $2.18 they where over three dollars originally, I decided I really didn’t need to enlarge my thighs with them and said never mind,I’m going home to make home to make homemade cookies, I then stepped to the cash register, at which point I heard Chris say what do you expect you get them for free? And she and the other girl laughed and laughed. I thought you got to be kidding just because I don’t want to buy your stale cookies is no reason to get belligerent with a customer and treat them disrespectfully , the store is always dirty , I found a penny on the floor that was stuck because it wasn’t pulled up because it was waxed over, because apparently the floor wasn’t sweept property in the first place. . when was the last time this store was inspected?
So since these two insodents I have obtained what I need else where, and I believe in my best interest to no longer shop at this store, there are 4 gas station and a Dollar general to shop at in town, to purchase what I need, and after these two situation s I am going to stop shopping at Dollar tree also since family Dollar owns them also I believe.
