JRand, that is amazing that the Comcast guy did not use the correct hook up!
The only time I have cursed someone out (over the phone) was a Comcast customer service rep, and more than once. It took them SIX trips to get my cable hooked up. Half of the people were subcontractors and each person blamed it on the previous worker for hooking it up wrong. Each time I told them they needed to bring a very tall ladder or a bucket truck. Several times they left because they couldn't reach the line. Maybe they could have used A LADDER??? The last time they came out and almost left, Greg went to Home Depot, bought the biggest ladder they had, and after they used it, he took it back. (We spend so much $$$ there we didn't feel bad about it.) I missed 3 days of work waiting for people who strung me along all day and then never showed up.
If I had any choice on providers I would have given up on them long ago.
That said, I now have my internet service with them and it is 10 times better than mindspring, who just have given up caring at all.
