Customer Service is wholly non-responsive and ineffective

My agents and I loved kvCORE up until we had problems. We switched from one brokerage that used it to my own brokerage and was told they would import over our CRM/Leads/Sphere. Big Mistake!!! None of us recognized the names that came over and no one from our last 5 years of using was even there. When I called asking about it I was told they were company-owned leads and company-owned leads did not transfer. I assured them the former brokerage had no company-owned leads and as I was the primary broker for that company before opening my own shop I should know. The person I was speaking with said they would need to get the owner's permission to release our leads. Did I say, Owners? There is only one Owner, who are you referring to? The 2 names they gave me as owning the previous brokerage where we were I had never heard of! Then they said for $200 each agent they could get us our leads back. No thank you that is not what we were promised at the front end. So here we are Day 65 of the hostage situation and NOTHING!!!
