Incompetence

We sold a car to ‘we buy cars’ in May and to date the existing personalised registration has not been de-registered. This is after numerous calls and messages to the buyer, who kept on promising that the issue will be resolved. Yesterday he said he cannot help anymore and that we should contact ‘managers’ at ‘we buy cars’ to complain. He couldn’t even give us contact details of who to contact. In the mean time, we are unable to register the new vehicle with that personalised registration. Never before I have seen such incompetence. I don’t even know where to start or restart from here.
