I cant access my own funds due to a pending credit card ***** purchase!

I am a victim of credit card ***** on a card, which is still uncleared in my account after 10 days. The ***** department have to wait for the funds to clear before they can resolve the ***** case which can take up to 30 days! The ********** purchase amount, is frozen in my account so I cant use my own funds even though its an unlceared transaction that I clearly didn't make. So a ******** can easily use it but not me. This is completely unacceptable that I, as the victim, now cant use my own funds!!! Why is the onus not on the ***** department to actually investigate the ***** so they can easily see that it is an unauthorized purchase and release my funds for my use? The bank has allowed this to happen so they should take the risk of the amount.
