I was given an estimate for [£ ] but on collecting the vehicle the bill was [£ ]. Since we did not agree on a fixed price for this work I am legally obliged to pay only a reasonable price for the work. I have asked two other garages [names] to estimate the cost of the work. They quoted [£ ] and [£ ] respectively, [£ ] and [£ ] less than your final bill of [£ ]. It is clear therefore that your bill is unreasonable. I therefore wish to be reimbursed by the sum of [£ ] being the difference between what I paid and a reasonable price. I look forward to your cheque within 14 days, or other explanation of your extra charge, otherwise I intend to issue a summons against you in the Sheriff [County in England] court without further reference to you Yours faithfully
