Unbelievably unprofessional. If I could give 0 stars I would. I've been talking to the car buying group for a week to sell my car. I've given them all the information, took photos of damage on the car and agreed a price. We had to reschedule pick-up because I couldn't find the V5 form. That's where the trouble started. Next pick-up was scheduled for 5 days later, the confirmation email showed 1 month later. I had to make various calls and send emails to get the correct date. Once they came to collect the car, the guy (subcontractor, feel sorry for them) spent a couple of hours here going through all the paperwork, taking photos, calling them, giving them all the details, etc. I then got a call from the car buying group to tell me that the sales person made a mistake with the valuations. Apparently he got the valuation from a file they have from 2019 (which is a lie as I've had the car for 6 years and have never tried to sell it before now) and they could now only offer me £1,120 less than the original offer. They said it's human error and they're very sorry. I've told them how unprofessional they are and no wonder none of them will have jobs next year as AI will be replacing them and their "human error" excuse. I then got offered £200 more which was not accepted. All their email correspondence states no negotiations at collection, yet they arrogantly blame "human error" while trying to screw you over, hoping that you will feel sorry for the person that made the error. Very unprofessional.
