I have several problems. first the phone will have up for no reason. it will say there was an attempt to make 3 way calling when there was not. second it will say there was a system error and hang up it the middle of the conversation. they don't care when you call them to tell them your problems. i have been a customer with them for 8 months now and i have spent over 5000 dollars and they just don't care about there customers. also they have been over charging my calls!! please start caring about your customers because if there will be another way i will bring my money to them and i will tell everyone i know!!! read full review »
