ERROR Xre 03059

Several channels showing Error code XRE 03059. I called Xfinity and tech support had me unplug modem which was done prior as well. Plugged back in and channels were now coming in. Tech stated that the cause was due to my package was grandfathered in and had to be adjusted. Okay fine. Also said the issue would not happen again. Well, 6 hours later those several channels are showing the same error again. (Weather Channel, Local CBS, Several sport channels etc).
