!Dev related but still freelance.

So.. I do 3D stuff, scenes, animation and so on. The e-sport pub manager I know told me about this guy that wanted to start a local organizations around FIFA, hold tournaments at the pub and so on. He had some finance, contacts and needed a 3D scene of a stadium to highlight top placers as 3D Fifa cards.

Gotcha, so I hooked him up with said stuff, he was happy, manager was happy, first tournament went well. Now to the shit show:

He wrote to me a couple of days later asking if I'm up for more jobs, which k respectfully declined because l was on a bigger project that took about 2months to complete. Since that day, he spammed both me and the pub manager with request and wishes on wanting to do more.. and I mean SPAM!

Like the dude can't take a no, sorry. He tried to call on phone and messenger, messeged me several times / week and asked the manager of he heard from me.

Both the manager and I were perplexed of his attitude and after asking several times to stop and we both had other things for now (events / projects).. he.. he didn't stop. So.. blocked and that's that, right? Fuck now.. other clients of mine asked me if I knew of him because he tried to contact them to get to me.. like WTF?! How hard is it to take a no and move on?! Jesus.. client of hell in a nutshell
