Worst Company ever

This above company advertises how wonderful their system works to unlock phones etc. If their system does not work they refund you your money back, well they are not so wonderful and they are playing for time not to pay the refund back. Their emails are up and down with different stuff every time the last time it is a different system to unlock a phone which still did not work!! I ask them to refund they ask to do something else! Please people do not use their services when your iphone is locked and the previous owner do not know the Apple ID.
