Dessi Nikolova Review from Google

Dessi Nikolova's Review Sourced from Google
Attention! - Big scam!After 3 months of communication back and forth ( with multiple people) , I ended up paying almost $5000 for a website that looks like crap.Had to have a new one built since there is no one to take responsibility for the work they have done. After trying for another 2 months to communicate and “ fix” the website, I finally gave up. They needed more, and more money to “ fix” a simple informative site ( that’s all I wanted)… And since I had already invested so much, it was hard to give up and I kept hoping and paying more and more until they drained my account. Being unable to pay someone else, I had no choice but to try building the website myself. I went to Godaddy and did it! Turned out it was so easy to do - multiple choices of templates! I found one that also allows me to take payments and make appointments online. And I paid $179 for it. Beautiful website! Please save your hard earned money and don’t even make attempts to contact these scammers.This, by the way, is the only bad review I ever left for someone and that should tell you a lot.Good luck!

Rutledge Daugette Review from Google
1.0★
Rutledge Daugette's Review Sourced from Google
We had a great initial project with Ameex before they were purchased by Perficient. Post-support was slow, but acceptable, however as time went on, I stopped getting the level of communication and time itemization I was accustomed to. With Perficient taking over, things devolved pretty quickly, and despite multiple conversations with my account manager - nothing changed, even after bumping up hours to have more dedicated resources. Ultimately, I cancelled the contract this year. Disappointing because their team/work was stellar (and the development team is still solid) before, but the simple asks were continually ignored, and over time, I lost trust that I was getting the hours agreed upon.Towards the end, there was also what felt like a lot of gaslighting of my concerns, and outside of an initial project, I cannot recommend Perficient for ongoing support.Edit: I'm now bumping this to a 1 Star because I've spent the last 3 weeks digging into code and it's one questionable decision after another. Really poor.
