Subway complaint: Poor customer service

While I was trying to place my order I felt rushed by the employees and my sandwiches for my son and I weren’t made right. I was dissatisfied with the customer service therefore I wanted a refund for sandwiches that were untouched and still wrapped up. The employees told me they could make some more sandwiches but couldn’t issue me a refund which I thought was odd. I refused that offer respectfully and requested again for a refund instead. They insisted that they could make me new sandwiches again so I asked if there was a manager I could speak. Once the manager arrived to the franchise he told me the same thing the employees were telling I just think that it was unethical for him to try to force me to accept him offering to make new sandwiches when all I was simply asking was for a refund. After asking why I needed a refund He was very rude and unprofessional and wouldn’t let me explain why I wanted a refund because he kept cutting me off which was not ok. After he finally gave me a refund he also threatened to call the cops on me even though I didn’t give him a reason to warrant him actually needing to do so which I felt discriminated against because I was respectful and professional as best as I could be even though I was frustrated.
