OK , senior tech has left (Roger guy again never showed up). The result is that at long last Rogers is sending this problem to Comcast. Perhaps now that Rogers is actually trying to fix it (acknowledging the problem was the first step) we may now get some resolution. I told the head end guy I would send this msg so that all the people on this thread would know that something is finally being done.
As I have stated above on Thursday a senior tech (not the Rogers tech who was supposed to come and didn't for the second time in a row) sat with me and I showed him all the 4k problems. He spent time there getting in touch with the Rogers head end people and they finally realize that they have problems. The head end guy told me that Comcast was being contacted and maybe now there will be some action on these problems. I have been on their case for two months with no "support" and the presidents office has been notified of the abysmal "support" given Ignite.
Hopefully now that the problem is acknowledged something will be done but stay tuned.
BTW I showed the senior tech this forum thread to show him that I am not the only one with problems. Seems that Rogers has this forum to placate its users but does not read or react to it at all.
