Reckless, driving. Bad customer service over phone

I called the customer service line to file a complain about a reckless driver who was driving and Vancouver, Washington at 8:45 A.M. truck number 2337 or number 620 and I let the customer service person know that this guy was texting and driving and that he needed to be retrained. But they gave me a number to call 1-800-525-5555 I called the number and it didn’t work. I don’t know what’s going on the Xfinity Comcast but you guys need to get it together
