MyUS used to be a good company to deal with. NOT ANYMORE.
I was sent my package from MyUS with one item missing (In Review for package location). After 3 weeks I was charged $16.98 U.S. for mailing the item that had been in review.
Just received the package. It just contained the original package envelope in a plastic bag and some brown paper padding. The ring was NOT there.
I was charged another $16.98 for what should have been sent to me free as it was their fault it was not in the first package. I am at a loss to know how someone could pack this package and NOT realize that the item (Ring ) was NOT there.
I smell a RAT !!!
