MagicJack MagicJack.com MagicJack operates on fraud, supports only when you buy, any problem later you're sorry. Internet, Florida

On February 23, 2012 my MagicJack phone quit working. Attempts to contact them, left no business address, won't respond through email, get only recording with their #561phone, no 800 number. Only time I had a 2-way communication with their Live Chat was when they sold me the product, which even today, I found that to be true if I would only buy the new product called MagicJack Plus. Otherwise, you spent hours and hours hoping some Live Tech would  respond. Never happen!
Earlier problem, I had no use to a second unit therefore it was returned using the same package it came in. I never heard from them since, hence refund is forever gone because they don't respond to anything!
Not being able to get help to use this phone again, I already adviced my credit card company from now on, any future charges is unauthorized and hoping to get a refund due to breach of contract and for using it only for 5 months. My question is: How can this company operates its business and get away with this blatant violation without being censured or penalized by the Department of Labor!
