VPN Issues

I have spent numerous hours in the past two weeks trying to resolve the issue with my VPN dropping. It occurs intermittently on my work laptop and my IT department said it is my ISP, Xfinity. After speaking with Xfinity it must be my work laptop. I don't feel like Xfinity is addressing the issue appropriately based on the other posts I have seen. As a customer who pays for a service, I should not be expected to purchase additional equipment in order for the services to work properly. I now have a tech appointment scheduled but I'm sure it'll waste the poor technicians time as there is no known issue according to Xfinity. Is it suggested to find another ISP?
