The worst decision I ever made was to pick up the phone when someone from Vocus called. The moment they viewed me as a warm lead they put me on some list to continue to call me day and night and harass me into one of their products.
Thankfully I never signed anything, or returned any contracts. You would think that would dissuade them from contacting me, nope. It's been over a year, and I still receive constant streams of emails and calls. The worst part is they always call from different numbers so I can't add them to the do not call list.
Never, ever work with this company. They're the worst organization I've ever come across. Steer clear or they'll NEVER stop harassing you.
