Severe packet loss

Pls schedule a maintenance Comcast outside technician to either replace the underground cable or swap my route to another Comcast server as it’s likely a malfunctioning Xfinity hardware. 

I’ve had 7 service calls to Xfinity this month to try to solve this packet loss issue. This is critical to me as it’s my business to stream online and I get severe video lag and loss of internet 

1) I’ve already bought brand new router and brand new modem. Also upgraded to 1 Gb Internet speeds

2) Reset both hundreds of times. Am using direct line not wifi. 

3)Xfinity technician has already visited and he said he replaced inside equipment, outside equipment and even went up the telephone pole. He said next step was for outside technician to replace underground cable then to also reroute the hops to different Xfinity servers

Please help! I desperately need to fix this as it is affecting my business

Pls schedule an outside Xfinity technician?

thank you,
