Comcast unable to resolve MDD and T3 Timeouts causing several outages daily

Hello all,

I've been having this issue for the last three months and it has now gotten to the point where our internet drops multiple times per day for anywhere from 1 minute up to several hours.  We have had three technicians out to the house, and I have spoken with over 10 phone operators and has shared the information below.  I have replaced our modem twice, router once, the entire length of coaxial cable in my house (which is a single cable with zero splitters, amps, or anything else in-line).  I have also replaced all network cable with CAT6 shielded cable as requested by Comcast.  At this point everything has been replaced in my house and the third technician that came out today literally clipped the ends off of the coaxial and re-terminated them in a new Xfinity box, attached it to my house and said I'm all set.  Not even 30 minutes after the tech left I again had an outage which resulted in the errors below in the event log section of my modem.  I think at this point I will be switching from Comcast as this appears to be an uncorrectable issue from them.
