Sucks you have to go through that mate – Agreed with what the other’s said. Never take it personally, people are just having shitty days/ weeks/ years and taking out on the closest person. My advice is believing in the “selling by the number’s” strategy. Just make the calls you need to make to book the demo’s and call it a day. The next call you make after the shittest call could be the biggest deal ever :). Stay strong buddy!
