Old Navy orders

Anyone had their Old Navy orders delayed and subsequently informed that your orders are OOS?

I placed my order on the 23/11/12, and today, they informed me that out of the 7 tees, 3 are OOS.

I find this ridiculous as, they took 2 weeks to process my order which led to the stock out.

What makes it worse, was I contacted their customer service on the 25/11/12 and since then have had 18 email correspondence and many empty promises.

I was first informed that my order will arrive on the 7/12/12 and my credit card was charged. But now they are telling me that 3 of my 7 tees are OOS AFTER charging my CC.

Man, this is a terrible experience with them. Any advise or experience with them to share?

Thanks
