You've been wronged. The best you can hope is that the recipient of the letter takes it at face value, investigates and let's you know the outcome. The response (if you get one) may not be the apology or report of other positive action you are expecting though - prepare yourself for that.
You may not get an apology. But the MD/Transport Manager of the firm will be well aware that some of his employees are in the habit of using company vehicles in a crap sort of way. So, even if you never hear from the firm, you can be pretty sure that at least on of their drivers will!!
