Has Embarq done this with others as well?

We came to Las Vegas in May, and Embarq assured us that we could get high-speed internet in our neighborhood. We signed on, and the speed started slowing down to nearly dial-up lethargy. Because I couldn't get on Jeff's Embarq line wirelessly, I got a second line, and that one was not quite as glacial in terms of speed, but it wasn't fast. What both lines were was expensive. We needed to call out several technicians over three months, and each one told us that the reason that Embarq was slow is that our neighborhood was too far away to get the fast service. Each time an Embarq serviceperson said that, we contacted Embarq's customer service center, which denied that we were too far away. After spending over $700 on Embarq repair calls, we gave up and switched to Cox for our internet service. I'm wondering if there are others who have had the same problems with Embarq. If you have, please let me know. Thanks.
