Call clarity was always fine, but at cancellation I was put through the same thing. I sent in the correct power adapter. They said it was wrong, we're going to charge $7 for a new one.
"The $99.90 is the Unreturned Equipment fee. You returned the ATA but did not return the correct power supply, thus the ATA is not in "usable condition" per the TOS you agreed to:
"6. EQUIPMENT. In the event of Service termination by either Subscriber or Phone Power LLC, Subscriber must return to Phone Power LLC all leased equipment (ATAs, routers, phones, etc), including the original power supplies, in undamaged, usable condition at Subscriber's expense within thirty (30) days of termination. In the event Subscriber does not return the leased hardware to Phone Power LLC in working condition within such thirty (30) day period, Subscriber must pay ninety-nine dollars and ninety cents ($99.90) plus applicable taxes per unreturned device to purchase the ATA(s) or combination ATA and router(s) from Phone Power LLC.
"Per previous e-mails that were sent to you on 08/03, 08/06, and 08/13:
You may either return the correct model, or reply to this message and authorize a $7.00 replacement power supply fee, which would be charged to the credit card on file.
soooooo they charged me $99.90 instead of $7 for an adapter. They won't fix it either... it's a "well that's what you agreed to" thing.
