WebWolfs Reviews & Testimonials
Aayan Mushtaq's Review Sourced from Google
I hired Webwolfs, a Pakistani marketing company, for a simple task that should have cost around $100–$200. However, they charged me $2,000 for it. The quality of work was extremely poor and nowhere near the value they claimed. When I asked for a refund or even an explanation, they stopped responding completely. I live in Florida, USA, and have already reported this issue to the FTC and other relevant authorities. I do not recommend working with this company — please be cautious before doing any business with them
monish shandil's Review Sourced from Google
If I could give zero stars, I would. This company misled me into paying an outrageous amount for a website, promising quality and service that never lived up to expectations. When I decided to move my site elsewhere, they tried to charge me $400 just to buy back my own domain—something that originally cost $40. This is nothing short of a scam, preying on people who aren’t aware of the fine print.If you’re considering working with them, be extremely cautious. Read the terms carefully and be prepared for hidden fees. There are far more honest and transparent companies out there—don’t waste your money here.
Salman Habib's Review Sourced from Google
Their web design team created a blog site that's brought me great leads, and their SEO guidance has trended my posts. Now, I'm living the blogger's dream :). I will definitely recommend these guys
