Union Telecom USA is a big cheater. Their telemarketers keep calling you till you sign up. They also boast of the lowest calling rates to India. When they called me, they boasted of the lowest calling rates - 3.9 c per min for India. They also promised free 100 minutes per month for the first three months. When I asked about rounding, they said its 1 min rounding. Hearing all this, I signed up. However, later I found that they have 3 mins rounding and also they are charging lot of taxes.
I tried to reach their customer service but have not been able to reach them despite multiple efforts. Their online chat agents are always offline. if you try to register a complaint, you will get an error in spanish. Since I do not know spanish, I can't understand what the error is, but I have not been able to register a complaint at all.
They have also charged me $40 as refundable security deposit which I am not sure whether I will get back now or not.
i would recommend to stay away from union telecom. DONT EVER TRY THIS.
