Canceling Verizon's DSL

So after trying enough times to contact Verizon unsuccessfully, I've decided to cancel my account. Its disappointing to have them be so unprofessional, I guess they just don't care about the lowly DSL customer.

I sent them this email this morning:

Hello,

Please cancel this DSL account. Every time I try to call you, I get disconnected. Its not worth my time.

I sent it to billingservices@verizon.net, an email I found after 15 minutes of searching through their site.

UPDATE - This one didn't work either! I had to call them again to finally cancel my Verizon DSL.

Response from Verizon

In response to my last email to Verizon, this is what they sent me:

We apologize, but you have reached an email box that does not respond to incoming emails. It is not monitored.

However, your issues and questions are important to us.

Please visit our Verizon Online website at :

To send an email or chat with a representative, please click the help tab at the top of the window, and select the "Contact Us" link on the left-hand side.

I don't understand how they can stay in business.
