Yeah, I had something that REALLY pissed me off happen a little while ago.
I rented my modem from Mediaone Roadrunner. They got bought out by ATree&Tree. Soon after that, I got a "buy your own modem" offer, saving me 10 bucks a month and a good 20% off a modem. Great, I thought. So the shiny new modem comes, and I fill out the form to have it activated. This is supposed to de-activate the old modem. After 4 days, it was still working, and the new one didn't work. Ok, I thought, they must have mis-read the form and activated the wrong modem.
I call their tech support, which entails about a 45 minute wait, and have them activate the new modem. Nothing happens. Old modem still works. Next week, call again. Get competent guy. Old modem dies right away. New modem will not work. I have him re-activate old modem.
I call manufacturer to return it. They insist that I troubleshoot the modem first (ok, that's fair...), but MODEM IS NOT ACTIVATED. Have to call up AT&T again, wait 45 mins, just to activate the damn modem. Call manufacturer, wait only 5 mins, and go to tech support. No, we can't let you return it, modem is good. Oh wait, do you have any filters on the line? Oh, you don't get TV, only Data? Oh, that's probably the problem.
Call AT&T again. They finally acknoledge that there are some filters that may affect line quality. They chose the old brand of modem because it had low sensitivity to those filters. (so why did you offer me the new one?) Go through conversation, discussing costs of removing filters, etc. Find out that if I don't get the modem to work after the filters are removed, then I will be charged for a service call.
That's it. I return the modem, and try to end this bullshit.
Motorola insists that I try one more time, so they offer to replace the modem for free. That means, when the new one comes, I'll have to go through this shit AGAIN!
Sorry for such a long post, but I had to get it out of me.
