B2B Review from Greg Digneo
Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.
BPO Review from Nimmit Shah

The representative was awesome. However, I still have to wait 3-5 business days for my provider account to be added so that I can write prescriptions.

J B's Review Sourced from Google
They are simply crooks. I told them multiple times to cancel my subscription and they continued to charge my credit card. Over $1000 in stolen charges. Hours on hold with a ridiculous inept customer service system that ran me in circles. I finally had to cancel my credit card. My emails were ignored. Stay away from this company.
