to the correct address?

I placed an order about 2 weeks ago and paid thru paypal. Somehow I didn't get my order. I checked with UPS and it turned out the stuff I ordered got delivered to my OLD address! I was pretty upset especially when the invoice showed that it had my current address. I contacted UPS and they said they send to the address provided by the shipper.

Well, in my paypal invoice and the confirmation email I got from curlmart, my current address is what was shown. However, that is not where my order was delivered.

Luckily I was able to get my package b/c nobody has moved into my old house yet. I would like to continue ordering from curlmart but this last incident has me a little scared to order again. What can be done to avoid this?
