Things That Make Me Say, HMMMMMM?

I Hope This Makes Sense?

So, companies have multiple divisions within their org and they all need the sales department to help grow said company. So! why is it when we call/email/social those other divisions they never answer their phone/call back, reply or they answer with not interested, we're all set? I mean if you want your sales peeps to be successful then how about give the rest of us the time of day, thoughts, concerns?
