Firestone Complete Auto Care

On 06/01/2021 I had made an appointment to take my care 2013 Jaguar XJL because I had a leak. It took them an hour before they looked at my car even though I had an appointment. Then it took them 4 hours before they returned and said that I need a water pump. I had a warranty on the car and I gave them the information to contact them. They did not contact them until 3 days later (06/04/2021) and when they did it was after hours and on a weekend. On the 7th the ordered everything and they repaired my car the same day I called them and said that my car smoking and coolant light was on and that said that the smoke was from the residue from fluid change out would burn off. The next day I added fluid level because it was low so I took car back and they could not attend to the car because they were booked and the only time that was available was Tuesday the 8th off June. Now that is 2 days later which I had an appointment for 10 30 and did not see my car until 12 45 at 3 00pm they said that I have a gasket leak and they needed to keep the car it is now the 23rd of June and I still do not have the car I keep on getting excuses. I have already paid 573.74 on the 11th June now they have had my car with in this month 21 days. I have just moved here and I have had to post pone 2 job interviews and several VA appointments could some please help me with getting my returned to me.
