XRE-03059 errors for the last week or so

We have COX cable and internet in OKC, OK.  We have been getting this error message on our cable boxes when trying to tune various channels for over a week now.  Sometimes we can tune away and then back and it will work but usually we cannot tune to the channel having the problem for hours or days.  I have used the app on the website to rest every box in the house and have gone around and have power cycled every box on the house.  I have checked all connections and nothing has changed in the house during this time that should lead to problems with our cable TV inside the house.  In addition, we often have "pixelated" video that reminds me of the images that you get when using satellite TV that is encountering signal interference.  I have also noticed an increase in the number of T3 timeout errors on our cable modem leading me to believe that there is an issue on the COX side of things in either the cable plant or networking equipment.  The COX website indicates that there are no service issues in our area, but this is clearly not the case.  Any thoughts or should we just look at another provider?
