I went through the same experience of needing, or wanting, a landline. My cell bill had been so high I was determined to find a cheaper option. Thinking I could just order from Qwest, who seemed to have the cheapest basic/local rate plus installation, i was later proved wrong.
After waiting for the date Qwest said my landline should be working, I was so excited and kept testing the line a couple times every hour during the evening (ooh, my first landline!). When I didn' t get a dial tone, I used my cell to call and ask what was going on. They seemed to think that it should work anytime and told me to try again the next. So, repeat this all tomorrow to find it still wasn't working. Soon, they sent me to some technical troubleshooter cs rep who told me the line was down and they'd have to send a technician out to ck it out. There was a catch though, the tech would cost me near $100 to come fix the line if the problem was something like 50 feet near or on our property line and it would cost nothing if the problem was on the lines b/w the telephone poles. So, full of an already building frustration from a high cell bill & my new and much anticipated landline being broken, I was so upset that they were basically telling me I was forced to pay this extra gigantic fee to even start svc. After several phone calls to diff. cs reps and finally speaking to a manager about the fact that someone should be warned about the possibility of an extra fee like that before they commit you to all the start-up taxes/fees of even ordering a new phone line (yes, separate from that technician fee), I finally got them to cancel the phone line and not charge me the cost of ordering this service that I never even got to use!
I will never order Qwest ever, ever after having to go through that ordeal and, though a little unfamilier w/the whole cable/phone line/Vonage deal, am even willing to try that to avoid this provider. So, yes, if your line is cut, definitely ckout what other landline providers'll charge for repairs or go for the cable line! :)
