Thanks for the advice @dgmx5 , I was thinking of doing exactly that.@slay , if the contract was that the London Co sell the car and that they will be paid £y to include commission and disbursements for the sale such as detailing, warranty etc and then they sell for £x but disclose they sold it for £x-2,000, then on the face of it they have made a fraudulent or neglugent misrepresentation to you, or are in breach of the terms of the contract.
As the sum involved is considered a small claim, I would suggest writing a letter before action explaining why you believe they have failed to pay over £2,000 as agreed in the contract, and give them 28 days to either pay or give their reasons why they consider they are entitled to retain the monies.
The advantage with a small claim is that legal costs are generally very limited as to what can be recovered, unless there is a clause in the contract where you indemnify the London Co for their costs if you bring an unsuccessful action against them.
There is no need for you to incur legal costs on such a matter.
If a claim is still necessary, it can be easily lodged through the Money Claim Online website. Feel free to PM me if you require any assistance.
The sales director called me (probably because the review I left on Google) and tried to explain this away as "miscommunication" and how returning the 2k would mean that they made a loss on the sale ...etc. He then "reluctantly" offered me a 2k credit for future service - I doubt I would ever use them again, so pointless really.
Thanks for the suggestion, I will write to them to demand the return of £2k, I think filing of a small claim would require some efforts and communications to try and resolve the issue.
I don't want to be harsh on them, but they need to know this kind of tactic is not acceptable, I am sure many others have suffered from the same tactic but never knew about it.
