And I WON! Here’s their response.
Don’t buy any products from www.vonage.com. This company is a complete rip off.
They charged me $129.00 deposit on the router that I got with the service. I intended to return it but, they won’t accept it back so you know I’m not getting that deposit back either. SCAM
As of today I have tried to cancel my service 3 times in the last 3 months. The first two times they said, “OK we cancelled your account”. Later that month we got charged for monthly service again.
I have filed a complaint with the FTC and they have returned my call to get my account information. There has been no further action by the FTC.
Today they called us to collect on the account that should have been closed in March 2010. Vonage has internal records showing our cancellation attempt which was verified on the last phone call to cancel service. I had to cancel my debit cards at the request of my bank.
Ticket Number #24783726 was created today and Robert #59559 from customer service say’s it’s 7-10 days before he can help us.
Customer Service was so unhelpful. They consistently blame other departments.
I recorded the last conversation thanks to my helpful iPhone. :)
