I’m not writing this asking for help, I accept that I made a mistake and learnt from it.
Just posting this in hope other people new to Fiverr don’t get in the same situation I was in.
I had a buyer pick my cheapest gig and sent the requirements, the requirements were clearly complex enough that he should have chosen one of my more expensive gigs. I told him that the requirements he sent me are not for the gig he purchased, he promised that he’d pay a large tip for the work to make up for it. I trusted him and went ahead and delivered the work for him.
Well as you guessed, I delivered the work and didn’t ever hear back from him.
Unless the buyer is a returning buyer or you having an existing relationship, be very cautious with being as trusting as I was.
