Hi - My name is Lori and I am a loyal Spirit customer..I am a member of Frre Spirit, the $ 9 Fare Club and even have the Spirit Mastercard that I use all the time. I flew Spirit this past weekend and I am seriously devastated by how I was treated.
On March 28, 2012 my husband and I had tickets for FLT 600 FLL - ATL confir # O8REQW. We checked the flight status and it appeared to be on time on hour before the fllight. Upon arrival to the gate we were informed that there was a 3 hour delay due to the plane coming out of Puerto Rico. We were extremely distressed at taht point because we had an appointment in Atlanta that if we missed would seriously affect our business. We asked the gate agent, Whilldring, what we could do and she said,"There's nothing I can do." We understood that but we were talking about getting to Atlanta on time. I got on my phone and found a Delta flight leaving in 45 minutes. We asked if we could check that and she said yes she would give us a credit for our flight if we wanted that. I tried to pay for the tickets on my iphone but it would not process asI tried about 5 times to put in my credit card number so she suggested we run to the gate. My husband asked how we could make sure we would get a credit if we got on the flight. She told us to give her our boarding passes and if we didn't come back she would know. We ran to Delta and there was a huge line. We missed paying for the flight by 5 minutes and had to go back to the Spirit counter and they said a credit was already issued and we had tobuy to more tickets to get back on and now they were $300.It was a matter of 20 minutes and we never said to issue the credit incase we couldn't get the Delta flight. The agent at the counter got a manager, Elvin Vazquez, who was NOT very pleasant and told us there was nothing we could do but give him our credit card and pay $300 for the tickets. I told him we did NOT tell her to issue the credit until we saw that we could get on the flight. He called the gate and made her come to the counter and she had the audacity to point her finger at my face and say,"That's exactly what your husband said." She then laughed and walked away. I am really flabbergasted that loyal customers were treated this way. I asked for her last name and the mangaer E. Vazquez said, "You live in America and Idon't have to tell you her last name!" What does that mean even? The $185 is worth such poor customer service? I cannot believe how we were treated. Why would we give up our tickets not knowing if we could get on the Delta flight if we still had 3 hours before the Spirit flight left? They basically called us liars and told us it was too bad...
May I please hear back from someone concerning this situation?
Thanks very much,
