I used Fiverr for assistance with a few smaller jobs. Some gigs were helpful. Some were not. But when I needed assistance with a larger job building a wordpress site, the experience was timely and costly. The seller asked me to review and complete the order before the work was done (this is a common problem on this site). Doing this means the job is complete and the seller is no longer obligated to finish the job. This seller attempted to communicate with me on my social media sites rather than on Fiverr. I didn't allow this. I wasn't able to use the wordpress website I ordered due to poor programming. This was partially due to a language barrier and several misunderstandings. This was frustrating because when I ordered the job, it was stated English was spoken fluently. When I left an honest review the seller harassed me until it was changed. It was highly unprofessional from a person claiming to have experience along with education in this specific area.
I feel some sellers on this site offer a good product. And I have had very positive experience with some sellers on Fiverr. But, the site does not appear to check sellers backgrounds. I don't feel it's a safe site to use for assistance other than with small, basic jobs.
