Pick and Pay Payment ****!

Just got ****med today by Pick and Pay. Bought stuff online received not all my stuff and was told to wait 3 to 5 business days before I get my change on the original amount back because I was " Charged less of sold out items " right so why do I have to wait 3 to 5 days for my money back????? Are you mad! Please never buy from them they are ****ers!
