The team at symbont group are great to work with - they have helped us improve our lead generation by more than 50% in just 6 months! They know their stuff inside out so we get amazing results every time; I can't recommend them highly enough for your needs of generating leads from cold calls or social media posts/messages into qualified warm prospects who want what you're selling (or could be persuaded!). We've had some fantastic success stories as well which has been really rewarding- keep up this good working relationship it will pay off :) There's nothing specifically i dislike about my experience but if there was then maybe its being able t do too much automation within campaigns? Be sure when choosing an outsourcer like these guys make certain everything runs smoothly otherwise things may not go according plan / timeline etc.
