It’s because it comes out of the blue titchy, and is also followed by ‘then there’s a second email, this time threatening to contact my 14year old at school’.
Whatever happened to a polite phone call or first email / invoice? Eg Otha’s come to my notice that x had not paid for this course which took place on x date. It is now x days overdue so I’d appreciate it if you could pay immediately by cheque or bank transfer. Blah blah blah.
Then you follow up with a less friendly one. Then notify of legal action.
Not one disorganised on the day cash taken with no receipt type of affair, weeks of nothing then these angry pseudo-legal emails directed to a minor!
Tbh if the guy is this disorganised, and doesn’t give out receipts at the time, I can’t see how he thinks he can then start screaming for money so long after!
It all sounds very unprofessional, and obviously he will lose any repeat business if this is how he treats his customers.
He needs to take a course in both money management and dealing with customers.
I’d check with your teenager thoroughly about what happened, then reply to the email politely but firmly asking why you haven’t heard anything about this matter closer to the time, and explaining that you’ve paid. Full stop.
And this acts as a reminder to me that we should always ask for receipts no matter what the situation, because people can always decide to act like idiots further down the line!
