Business ProfileforSpirit Airlines

Contacted a spirit airlines representative about seating and purchasing additional baggage for my minor child. The representative told me I could get an already purchased seat credited back to me as there was no seat available next to mine for my child and that I could tell them I needed family seating upon arrival and that I could go online to spirit airline's website and use the credited amount from the seat to purchase the additional baggage. Upon doing so I was given no option to apply the credit and was charged the full $65 plus taxes for the additional baggage. I contacted spirit airlines multiple times about the issue and the representatives and supervisor I spoke to said I would need to go through their chat services to contact guest services to get the $24.18 refunded. I did so and was told by that representative they could not refund the amount even though I was given false information by an employee of theirs and when I tried to come up with another solution to purchase in-flight Wi-Fi with the credit I was informed that could not be done as well and that it could only be used for future flights or for things such as bags. I explained numerous times I tried to use the credit for bags and there was no option. I again asked for a refund since I was provided false information and was again denied. Spirit airlines has overcharges me and is refusing to refund the difference for the overcharges totaling $24.18.
