sprintunlockiphone scam-rip off Internet

I pay this company for an unlock. I get an email stating it had a bad imei number and as soon as I pay for a different service they will refund the first payment. So I paid the 70 bucks. Two days later I emailed because I never got my refund only the same email about three times a day saying I needed to buy the bad unlock service. It took about a week to get my refund and I email again stating that you haven't been unlocked yet. I get some response saying that towers or something were down and to give it another week. It's been two months now. No working phone no refund and they won't respond to my emails. Stay away you will get took
