Hi Aaron:
Time Warner usually gets good reviews so I was surprised to hear your story.
Generally if the reps take two months to come back with pricing, the company doesn't have its act together in your specific market. Your reps should have done back bends to make sure you were happy after the first issue. Datacenter clients are big money for carriers and sales reps.
I would look around for other options. The installation foreshadows your service level for the rest of the long term contract.
If you send me an email with your address and NPA/NXX, I can see what carriers are available in your area and their timeframes as well as an escalation list for each carrier.
Good Luck.
Dave
