The parking spot 2 - Love Field, Dallas, Tex

I parked my vehicle on 10/13/2019 returning 10/14/2019. When I went to pay my bill, I was charged for 3 days instead of 1 day. When I told the attendant I was overcharged, he gave me the reservations email. I have not heard back from them. I have called the corporate office, the local (Love field office) and Management office in Dallas. The Dallas phone number does not work; I've yet to get through to Management to rectify the situation.
