I have ordered many times on Kaidomain, communication is somewhat difficult, but i never experienced problems with them.
Just keep cool, count to ten (or 20 if necessary) and tell them your problem.

I have always received my items, and they are even willing to give some discount.
shipping takes long sometimes though.

Sometimes not all items are on stock, and they will just send the items which are on stock (without notification)
So they might have split your order, and you have to wait for the rest.

Also telling that the site is stealing your money is not legitimate and seems quite rude
(where did you leave the rude button SB ?)
