I worked in the accounts department of a hire purchase company many years ago.
We had a standard set of letters we used to issue to intimidate and frighten people who had fallen into arrears with their loans on normal small household items. The reason they were using our company was because many of them couldn't get credit or didn't have a bank account. The shop where they were buying the item from just got them to sign a few forms and their loan was approved by us. We used to charge extortionate rates of interest and never gave the APR only the simple interest rate.
(he funny thing at the time was that interest on an overdraft was tax deductible while hire purchase interest was not). When the account fell into arrears we used to issue them with a couple of letters, each one stronger than the last one and then we would issue them with a letter stating that we were handing their debt over to a collection agency. Then we would issue them with a letter proporting to come from that agency (there was no phone number on the letter and the address was a Box Number), then another letter saying that the collection agency had passed the debt back to us, then a letter threatening them with court, then a letter giving them 10 days to make a payment, then a letter in red writing with some fancy legal terms in it threatening court action, honestly the list of letters was endless.
When the account was 3 months in arrears we would get a rep from the company to call out to see the person, they had no problem calling to their place of employment as well.
Finally there was some central crowd (can't remember their name) that we used to post a negative review onto and that buggered up your chances of getting credit.
With the data protection act and all the other consumer friendly legislation I would hope this practice has stopped.
Not a very nice place to work but at the time, and being quite young, I suppose a job was a job.
