Mine were better:
1st letter from the parking co. demanding £120 with a 50% discount for early payment.
2nd from their “lawyers” demanding £120 plus costs etc etc.
3rd from a debt collection agency with the words “BAILIFF” on the front (really scared Mrs Gti, that one, I had a job keeping her from panicking and paying them.)
4th from a different debt collection agency suggesting I paid £80 to be let off, then 5th letter suggesting £50 to be let off, meaning they’d given up hope.
All of letters 2, 3, 4 and 5 bore the same crappy illegible computer-generated signature. I’m tempted to write anonymously to goad them but guess this might be unwise. In my case it was obviously some muppet sitting in an office in Rochdale feeding different letterheads into a printer and licking the envelopes in the hope that the hit rate would be enough to pay their wages and enrich the boss.
