I suspect that the driver is not also the owner of the delivery company?
And that maybe his boss was sceptical about his tale of "wrong address", maybe suspecting said driver had put the €35 worth in his own tank?
I reckon a letter from you saying you'll accept the unwelcome intrusion & ongoing hassle for the princely sum of €35 & offer to call it quits, will be enough to satisfy the boss & you'll hear no more.
