Trying to get help, but the automated system hangs up on me when transferring to a person

My internet is getting between 5 and 40 Mbs....I'm paying for gigabit.  There are also consistent dropouts.  In the past 2 days, while trying tech support on the phone, my modem has been rebooted 4 or 5 times TO NO AVAIL.  When the system tries to transfer me IT HANGS UP.  I am NOT happy right now, as we are currently working from home, and the internet is vital to being able to do this.
