      Lead Generation Review from Joachim Fong

      For the past year, Callbox has provided us with satisfactory lead generating and lead nurturing services. They were instrumental in securing attendees for our events, scheduling client appointments and facilitating the sale of one of our benchtop systems. Their professionalism in conveying our product attributes and valued solutions to prospective customers has brought us results.

      Lead Generation Review from Jonathan Anderson

      I’ve used Callbox now for about four months for my internet marketing company. The first two months they did not pay off. However with some additional training on my part, they started to close a higher percentage of my target audience. They’re really smart, nice and are really working hard to keep my business. My dedicated team keeps me up-to-date through frequent communications. My R.O.I is getting stronger and my CPA is starting to drop.

      Appointment Setting Review from Ted Calvin

      Charted Energy has enjoyed a productive relationship with Callbox. They have done a great job of helping us target prospects within the markets we serve as well as qualify leads and set up appointments with decision-makers. Callbox has generally exceeded the number of leads per week we expected and provides a good value by enabling our inside sales team.

      We are currently working with royal digital agency and I couldn’t be happier with the results. Their team is professional, creative, and responsive, delivering a series of ads that perfectly aligned with our brand. We saw a 25% increase in customer engagement within few months, thanks to their strategic approach and amazing team. I’d highly recommend them for any business looking to elevate their advertising game!

      I have been a client of Trust Haven Solution for approximately one year, with the company providing me with monthly check-ups and the occasional support whenever needed. I have been very pleased with the company and all of its representatives....professional and courteous and helpful in very respect. Certainly the best computer support service that I have ever used.
