I have never had a written contract with dealer I have worked on his vehicles for approximately 12yrs. It has always been I do the work and then present bills and he would pay towards end of month. But over the last few months I have not done much work on there behalf. So on this basis I presented my invoice about 7 days after the vehicle was returned to there customer. My customers immediate response was there was no more money due. The only money I have received up to now is payment for the replacement remanufactured engine which I purchased on his behalf from eBay for the sum of £2450+ VAT. This engine was a bare engine so all components from the existing engine needed to be transferred. This involved gaskets bolts, oil filters, timing chain flywheel and clutch and 4 second hand injectors. All these parts were authorised by his colleague James I have not done any work without prior authorisation from James. My total outstanding bill is for the sum of £2174.51 which I have not received and he will not enter into any conversation of any sort. I have received a letter from his solicitor saying that I must release the vehicle to there customer for with.
