Constant Outages

I pay for business class.  Yet I've been up all night dealing with a technical issue regarding a client's business.... and on the hour, every hour, my service is interrupted.  My PC VPN connection drops and VOIP drops for about 5 minutes and then comes back up.   A visit to my equipment closet appears to show that the connection on the modem indeed drops.

I thought Comcast Business came along with an account manager that could help you through the Comcast jungle.  I'm feeling alone, disowned and unappreciated by Comcast Business.  I don't want to call a help desk ticket in and get no help.  Can someone please help me??

Regards,

Dave
