itunes store Delete additional funds from my account upon purchase. Purchased itouch software upgrade for $5.33 total but itunes deducted over $8 from my account. From $34 to $26- stole $2+!! Internet, California

I have been carrying a positive balance in my itunes account of just over $34. I purchased a 3.1.1 software upgrade for my itouch system (won't talk about that outrageous issue) for $5.33 ($4.95 plus tax).

Apple itunes now shos a balance in my account of $26.59 which adding back the purchase would be $31.92 -- where is my $3+?

I have tried to send message to itune support and other Apple support but don't seem to be allowed to even compose message, everything locks up. I am fairly computer literate so don't think it is an issue on my side.

Apple just stole $3 from my account!
