Follow up with an email to them, as they don't have a customer service number. Its best to order items as priority. Mail, and not regular mail, so you can track the order. They are a company overseas, so you definitely want to order items way in advance to counter any delays. My order was one week behind but I did not need the item for quite a while. Again, track your order and email them with your inquiries

Good Luck is all I can tell you. I ordered my shoes and jewelry for my wedding in early February and didn't get them until late March almost April. I wasn't getting married until September so I'm glad I did order them so early. And hopefully your invitations will be correct and look good. I got lucky with my shoes and jewelry, I've seen some reviews where people weren't so lucky to get products that looked very nice.
