Subway

We ordered a foot long breakfast sandwich and was given a straight wrong order. The Mexican ady that was at the register was kind enough to say come back and I will make another with no charge. We came back while we were speaking with the "Manager" some lady come from the back and started to say " Next time make sure you order the right thing because this can be the store that will not return the order again." My reply" all stores will return if the order was taken wrong". her reply " I do not think so. I went to a place they did not let me exchange so I know so" our reply " The customer is alway's first and who are you to come from the back ofthe room and come be rude to a customer and not even know what happened? " her reply " I work here." Our Reply " Well you need to get your fact's straight before you come barging in with a high pitched voice to an elderly women telling her thing's about her order. We asked twice what size the breakfast came in and the lady at the register said only in muffin size". I went online to check and it was not true so I called the restaurant to make sure and the lady had a misunderstanding I guess. Anyways this ghetto chick need's to stop working at the restaurant she does not bring any happiness and is really rude. The so called manager is not taking any action and we did not get an apology just a dirty look from the broad. I was wondering who else I can speak to.
