I can never believe anything said by MyUS because they are scam. I will not beleive they are not scam only if my package is delivered to me. i have paid several dues coz they told me to do so, but i realised that they scam until when they told me to make a payment of 86 dollars for my shipping fee in which i accepted but before i got the money they had increased the shipping fee from 86 dollars to 186 dollars. They said the 100 dollars is for authorization. can you imagine paying 100 dollars for authorization. I have been trying to talk to there team for the past three days but they never call me back on there call back service when i left a voice note for them, i tried to use there live chat service but there Agent has been offline .......
