Please help me. in-app content drama. iPhone 3G

Hi y'all,

     I can't purchase any in app content. Keep getting the message "iTunes cannot process purchase please contact iTunes support.". Followed by an error 0 code can't connect to iTunes store.  I purchased a couple in-app content things yesterday.  Wells Fargo decided to take that as fraud. I called them this morning and cleared it up and made sure no blocks were put on iTunes. Ive contacted iTunes about it and no reply. My phone is not jailbroken,  I've updated, restored it, re entered all my Info, bought an iTunes card. Nothing works. My Credit card is no where near being at the point of declining. It's very frustrating.  Checked my restrictions, they're enabled. I'm at my rage point. I'm a long time apple customer and have invested a lot of my money and want to continue to do so because I enjoy having my iPad and phone to play around on. However, if I can't get this resolved I'm going to end up raging out, throwing my phone through a window and washing my hands of the whole thing. I really don't want to do that. Any help is very much appreciated!!

Thank you <3
