Santander Bank US Bank Account Or Service Complaint

Santander Bank US Bank account or service department,

Checking account Deposits and withdrawals Massachusetts

Upon having my debit card rejected when attempting to purchase a coffee, I checked my account statement online which read $ -. A check had been deducted from my account for $40000.00. I suspected check fraud, called Santander and was instructed to proceed to a branch. While at the branch, the tellers and I deduced that an ATM error misread my check for $40.00 and, unfortunately, nothing could be done. I demanded that this be resolved as soon as possible as I needed gas to return home but was told that the check had to be cleared before any action could be taken. This could take up to 2 business days. I asked how this amount could be automatically subtracted from my account with no alert, whether electronically or by phone and the tellers could not provide a sufficient answer. The teller then advised that I should have a credit card as a back-up for gas and I should have downloaded the Santander app. The Santander app would have alerted as soon as the check was deducted from my account. The teller further indicated that if I had acted sooner, ie. in the morning vs. afternoon, this problem could have been averted. It has now been 24 hours and I still do not have access to my funds and my account remains to be $ -.
