OLD NAVY is offically on my hit list!

OK, first of all my momma and daddy got me some OLD NAVY gift cards for my birthday.  They come in $50 per card.  So I get online and start shopping, because there isn't an OLD NAVY near me that sells maternity clothes.  Anywho, I get on there and I spend more than $50.  So I enter one card in and it takes $50 off my total.  So far so good...  Then I enter another card and it won't take the other $50 off!  WHAT!?!?!  So I figured they just do one card per purchase (which makes no sense, but whatever).  So I go back and shorten my order so it would be below $50.  So I redo the ordering process and it takes the $50 off.  So far so good... but there is like 44 cents left and I am like I'll just put it on the credit card and finish my order.  So that's what I do...  Guess what...  OLD NAVY is "currently unable to process gift cards at this time".  WHAT!!!  Are you kidding me!?!?!?  So I have had it.  If you see a big ole pregnant lady walking around with no clothes, it's me.  And to file a complaint...just write to OLD NAVY!  I'm sure they would get a kick out of that!
