False advertisement!!!!

I purchased an xbox bundle online as soon as it was available and got confirmation order was accepted and paid. Yesterday i get a package which was not what i ordered!! I only purchased this bundle because it was a better deal only to receive something i did not order spent all day yesterday on the phone only to be hung up on 4 times!! If the item was sold out then orders should have been stopped instead of taking them. Finally talked to someone this morning only to be told they could give me a $30.00 refund but i am missing almost $150 in products are you serious?? I can return it but it takes up to 15 days after they receive it back to get my refund?? It took all of 2 minutes to take my money and not give me what i paid for but you want to hold it another 15 days??? Dell should give me what i paid for and sot a $30 credit that doesn't even cover the cost of 1 of the items i was shorted!!!
