i have been a customer for 4 years with them,about a year ago i started getting phone calls 24 hrs a day throught the 800 number i had with them,the first time i contacted them they spent 3 hrs with me on the phone trying to block unwanted phone calls,in the end they told me they had done all they could,i asked were they were located and he said phillipines,i asked them to have some one from head office to call me about my concerns,he said they would,it  never happened,2 weeks later i called again and spent 3 hrs on ignore,i tried again 10 days later same 3 hrs on ignore,they just dont cars,they billed me on my cred card for 4 years for a 800 number they never hooked up,poor service,they are in business to ignore you and charge you,STAY AWAY FROM THEM
