ch was supposed to arrive betwee June 19 and June 24th, which I have not received yet.
And probably won't for another month.
Today is only May 25th.
You can contact the seller and ask:
When was this shipped? What service was used? What is the tracking number?
Note that you really just want some response. The purchase may not be tracked, especially if you bought from overseas and if it was cheap.
International tracking is very very expensive.
(If you ever, ghu forbid, have to return something to an overseas seller, it will cost you $40 or more with tracking.)
But most important, it's not going to arrive for a month.
It it doesn't fit in your mailbox, the carrier will leave a Notice telling you where and when you can pick it up.
This will be sometime in late June.
If the seller offers a refund, take it. You can repay using Paypal's Send Money service when it does arrive.
If the seller offers a replacement, ask for a refund. This is all too often a scam.
