I had an interesting experience in Wells Fargo around 2012. I had probably 10 business accounts there, including the main receivable account, as well as an account from which about 7 contractors were paid monthly to the tune of $100,000/mo. I was the only signatory to the account, the only person with a login. I had my personal accounts attached there as well. A some point I log in into WF from my regular office laptop (static IP) and instead of the account balances I see a warning: your access has been restricted due to security. Please call an 800 number. I log in from my phone via different IP, same result. My attempts to talk to the assigned business banker went nowhere: she repeated the same number. When I called that number, I got treated like a criminal, I got yelled at and I was told that all accounts needed to be renumbered, and the previous accounts would disappear including the account history. With multiple vendors and contractors, renumbering accounts is true hell. When I asked this person about the alternatives and for a reason for this action I was told that this was done "for my safety", and if I needed the details they could only be obtained via a subpoena. I tell her that according to my knowledge, a subpoena can be obtained only during a civil litigation, and I am asking her if she invites her customer to litigate against the bank? She rudely responds that if I do not want my accounts renumbered, she would leave this as as (with the security warning and no account access). Since this is business critical, I acquiesce and she removes the warning, but the accounts are read-only now. She then tells me that I need to go to a branch, killing my workday. At the branch a salesperson tries to sell me their new accounts and packages (that are of course worse than the original ones). When she realizes I am not an easy target, she just asks me if I am ready for the account renumbering. I ask her if my accountants will have access to the CSV - without this we cannot even make quarterly tax payments. She says sure. I ask her that just in case, I want to download the accounts (all 10 plus 4 personal ones). She says go ahead on your laptop (like I am paranoid, I don't need this). I ask her if they have WiFi in the branch. Not for me. No problem, I tether to my phone (for 2012 it was advanced) and download. Then she hits the button- the accounts are completely gone! Only the end balances got transferred to the new accounts. I leave. Then I call Wells Fargo and ask how I can get the CSV histories. A business Banker tells me that she can fax the hard copies of each monthly statement for $12 per statement per account! When I discuss this later this awful experience with my regular business banker at my branch, I ask her if higher balance accounts get treated the same. She says that my accounts (low 7 digit balance) are too small, but starting from 8 digit, you get a different treatment! I still cannot understand what kind of "safety" a new account number can provide, because every time I write a check I disclose my account number.
