Tarte customer service nightmare

I've tried to place an online order with tarte twice now and they keep accepting my order and then sending me (to my junk folder when all their other e-mails go to my inbox) an e-mail saying that my order was declined because my credit card info was wrong, however they've charged me for my order so that's not possible? Now they're customer service is being impossible. I just want my order. There was stuff that was on that order that was a one day special and other stuff that's limited edition and I just don't understand why they're declining me for no reason and telling me it will be 3-5 business days (a week) to refund me.

Anyone ever have any bad experiences with tarte? This is my first order with them and I'm so irritated with the amount of work it took to even get them to send me a generic e-mail.

UPDATE 45 or so e-mails & 4 declined attempts to order later they offered to just send me the order. (first offered nothing, then 20% off, then a 100$ gift card) I'm excited but not getting my hopes up after all these colossal fails) Still haven't gotten a confirmation e-mail saying the order is shipped. They also let me keep the 100$ gift card for my next order. If all this works out it will totally change my opinion of tarte. This experience has been an absolute nightmare of constant e-mails and lack of information or answers but no company has ever offered me my $150ish order for free and a 100$ gift card on top of it. I know they're a big company, but like I said I'm skeptical. I'm really really hoping they keep their word because I can't get these products anywhere else.

IF you find yourself in trouble with tarte I found you need to be persistent and stand your ground! They ignored my e-mails for days until I went to social media and started posting about my situation. It was really sketchy having a company withdraw money from my credit card then refuse to ship and say my info was wrong. The first few e-mails were generic and not very polite. However all the charges have been taken off my credit card and the above promises have been made. Will update if I receive the order!
