Hmmm... Sounds like you might be dealing with a sketchy situation. First things first, check your order confirmation for any contact info or order tracking details. If you paid with a credit card or PayPal, immediately file a dispute to protect your funds. Also, do a quick Google search for Manicci reviews or complaints, there might be others like you. Unfortunately, sometimes these smaller online companies just vanish, leaving customers high and dry. Hopefully, it's just a temporary communication hiccup, but be prepared for the worst and take steps to get your money back!
