Tech visit survey

My internet and cable service was out for 24 hours from approximately 2:00 PM EST on March 2 until the March 3. A technician visited on March 3rd, and found that someone from Xfinity had disconnected the cable from the street to my house, and had put a terminator in its place. The tech reconnected it, but found there was some noise backfeeding from my wiring, and replaced some connectors to get the noise to acceptable levels. There was NO RECORD of the termination at Xfinity and we were not notified. This caused a great deal of wasted time. The tech said we'd get a survey, but never did. Please let me know how to give feedback about this visit.
