Back again with unresolved high Power (dBmV)

I'm consistently sitting around the max limit of 10 dBmV and phone support don't seem to get the message.

My connections constantly poor, the modems always switching doing US profile assignment changes and when this happens, I lose connection.

T4 timeouts are common.

T3 timeouts are sometimes in the thousands.

3.1 Downstream channel corrected errors are now in the BILLIONS and a fair few uncorrected errors. 

You have replaced everything, cable to house has been done, internal cables have been replaced, repeated splitter swaps, the techs just do something to humor me and close the call knowing full well it doesn't fix the power issues.

I assume I've been put onto a higher tap to fix someone else's issue as it seems to be the norm when working in the cabinet.

I've had enough, I pay a fortune for a poor service and the supports never been able to nail this. The last tech who came said it's an issue that isn't related to anything after the cabinet to my house, and this was never followed up, just more excuses.
