CHASE They literally stole $100.00 of my unemployment check! Internet

Shell is "technically" correct in that the bank is the one who is holding the money.  But the bank is holding the money at the request of the gas station, it is not like Chase just randomly put a hold on your money.  It is also not like Chase can just remove the request on your word that it was an error. 

In your case the bank received a request from the station for two $45 holds.  Chase(or any bank) has no idea if the hold is legitimate or not.   The only way they would know it is invalid, is if the gas station either releases the hold(which they can do) or they notify Chase that the hold was done in error.  If the gas station does not do this, then you have to wait for it to "drop off".  Although, I am not positive that the 5 days the bank is telling you is totally correct, I think a hold can actually be in place for up to 10 days.

Situations like this is the main reason you should never use your debit card on things that put holds on your card.  These would include places such as Pay at the Pump Gas Stations, Car Rentals, or Hotel Stays.

Chase didn't steal any money from you and this is certainly not a scam.

When you swipe your debit card, the merchant places a hold against your account. That hold will stay on your account until either the actual charge is hard posted or no charge is actually submitted in which case the hold will expire after a few days.

The gas station placed two $45 holds against your account. That isn't the bank's fault. If Shell refuses to fax over the paperwork then your problem is with them, not Chase.
