Carvana complaint: Delay of Promised delivery date caused financial impact on customer

I initiated a purchase for a vehicle with Carvana and had a delivery date of 6922..In order to get paperwork completed for timely delivery, I was asked to change my registrationplates over to the purchased vehicle – ing me to get rid of my old car and being without transportation. Apparently there were mechanical issues on the day scheduled for delivery and this was rescheduled. A second attempt at delivery was not possible until today – 61522 – almost a week later, but understanding this was an unfortunate setback, I waited. I have been without a car, paying for transportation and finding rides to work, and daycare for my kids for a whole week to find out this morning that the car had more mechanical issues and the delivery date had to again be changed. I am planning a trip next week and will not be around for the said date. I have pleaded with multiple Carvana staff to help me with a replacement vehicle – all which are too far out of my area and delivery costs are outrageous. No one has been able to help with this from Carvana. I spoke with a manager on Friday 61022 who promised I would have the car delivered on Saturday, only to tell me the day of that there was a problem with the computer system. I provided Carvana everything they requested timely. This is a HUGE inconvenience that has affected me financially, only to find myself being told by the staff to go through a regular dealership and they could not help me at this point unless I am willing to wait until the end of June when something will become available.
