POOR service and UNACCEPTABLE outcomes

I app**** for finance on a vehicle at We Buy Cars Midstream Branch, with the knowledge that the vehicle is reserved for 72 hours as per their policy, for another customer, so I filled an online application for the vehicle, and they did an application for finance after the 72 hours has elapsed. When I phoned to get feedback, the car was suddenly not available to me anymore because the other applicant paid to have the car fixed, as per the words of the sales executive, NOW, the car has a gold Dekra sticker, which indicates ZERO faults on the vehicle, so why would there be a repair which was paid for in advance? Secondly, why would you, when knowing that there is something like that in progress on the vehicle, proceed to apply for finance in MY name? I would NOT recommend working with these people as in the first place, they do not know what's going on in their warehouse, secondly, applying for finance on your behalf on a vehicle where there is suddenly issues with when you start to question why you are not getting the vehicle, and in the third place, the vehicle is the described to you as a car with a lot of faults according to the sales executive, with a golden Dekra sticker on the windscreen, which then implicated that Dekra is handing out incorrect evaluations on ALL We Buy Cars' vehicles.
