Jack, also 36, claims he is owed £7,079.81 for work on jobs including an advert for a well-known hotel chain and a mystery, Mrs Sidhu Investigates.
With a young family, every penny counts for Jack - who works another job for an events company.
In January, he had to chase Archie for a second instalment for the hotel ad, having received “the mother of all tax bills”.
Archie said in a later WhatsApp message he would send Jack £2,000 of his own funds, to avoid Jack “stressing”.
“I’m more than happy to do that, if it takes the pressure off you at the minute - until it comes in,” Archie said in a voice note.
“That actually made me a bit emotional, because I was like, wow, you're going above and beyond for something that's not your fault… that's how I saw it at the time, naively,” Jack says.
Archie had in fact received payment for the job in October 2023.
“[Now] I feel isolated, alone, left in the lurch, but I’m also angry. He will do it again - because why wouldn’t he?” Jack says.
