Salesstaff pre sales pitch was good but we did hit bumps all across the campaign period after signing up with them. Not even 10% qualified appointments were made by their team. We provided proper feedback on all appointments on the same day, but it fell through the crack because of very poor account management in the beginning. Salestaff tried to fix the account management issue later, but we suffered at the end of the day. Overall, almost zero ROI on our time, efforts and financial investment with Salestaff. Not even a single sales was done through Salesstaff lead generation campaign.
