Internet keeps Dropping. Need Help

For a month now my internet will frequently drop throughout the day.  It dropped 7 times today. Losing my patience with Comcast.  Takes forever to speak with an actual person. Went thru the chat 2 weeks ago they scheduled a tech and the tech never showed up. Called again and said they had no record. Schedule for a tech again. Tech said could not see any issues so recommended changing my modem. That did not work. I have another Tech coming tomorrow.  I want this situation elevated.  Just like everyone else I pay to have internet. Working from home and dropping from calls through the day is beyond frustrating. Need some real support here Comcast.
