Subway complaint: Terrible service

I initially went to Subway on 811 before my shift and they didnt toast my sub even though I was asked and said yes. I came back on my lunch at work to get a remake. There was different staff but the first kid said he could just take all the toppings off and toast it. Gross. there’s mayonnaise on it. I gave my receipt to the cashier and ge asked me for the old sandwich for inventory purposes he was so facetious. I called him a liar. This kid had his mask down, and went to cut my sub vidictively off center. He told me he didnt have to serve me. Then I demanded old sandwich back. He looked at the other coworker and said she can wait I demanded sandwich and the other kid goes, Ma’am, I’m trying to help a customer right now which was the lady behind me. The manager came up, threw my sub away and refused to give me my receipt and the sandwich I im initially paid for. She wouldn’t let me speak, she just yelled at me like I was her kid. Instead of professionally defusing the situation- she threatened to call cops. I paid $13 for a sub meal I could barely eat
