No doubt, Vonage Holdings (NYSE: VG) was one of the worst IPOs over the past year. The company must also deal with patent litigation with the mighty Verizon Communications (NYSE: VZ).

I've actually been a customer of Vonage since November. But, today I cancelled my service.

Things were fine -- that is, until my router failed.

So, I called up Vonage and got a customer care representative (who I could barely understand). Basically, the company would send me a new router but I would have to send back the defective one.

By the way, I also told them that my address had changed.

Well, Vonage did send out the phone – but to the wrong address.

Despite their mistake, I have to call DHL and somehow locate the phone. Or, if that doesn't work, I have to file a police report and fax it to Vonage. After that, I will then get a phone.

In the meantime, I guess I just have to use my cell phone.

That didn't sit well with me and I cancelled my account. As a result, I will be charged $109 for the router (that was sent to the wrong address) and $39.99 for the cancellation fee.

Nice, huh?
