This is my first time dealing with MY US and I dont know whether it will be the last or not .
I submitted and paid for my order SH-645680 in August 29th with a rush processing fees but unfortunately after 56 days I have not received neither my order nor a reply for my 5 or 6 mails explaining why all this delay and why no response to my correspondences from MY US support or customer service .
I hope that I receive a reply from the owner explaining and solving my problem ,
