Legit Greenacres service is awful

The service that I received at Legit in Greenacres was so unprofessional and the two tellers were really mean. The first teller couldn't not believe that I am purchasing with an account. Apparently to her I look too young to have an account and it was not the first time shopping at this branch. She kept telling her colleagues that I'm too young to have an account, fine I took it as a joke until she asked me to sign a slip of which I did but the signature was different from the one on the back of the card. The teller that was helping me called an old lady who works at Legit and this lady told me that this is not my account. In front of other customers looking at me, basically I was called a *********. I was so mad and I have so many accounts under my name and I have never been this disrespected and judged as a *********. This old lady had the nerve of telling this other teller to write down my ID number. I understand that it's their job to do ***** checks but they can't just go around a cussing a client of ***** its even worse infront of clients. I have never felt so humiliated. It's a pity other Legit stores close to me were closed down.
