Westlake Financial services I have an account with Westlake, but they accessed my son's bank account and withdrew money Los Angeles California

 I have had an account with Westlake Financial since August of 2015. Never been late, always paid on time, never had any trouble. Yesterday, my son came to me, and asked me how Westlake Financial took $135 out of his bank account. He has no ties with Westlake Financial, has never had an account with Westlake Financial. But somehow, they found a way to access his bank account and take $135 out of it. My son has a different bank then I do. So someone had to do some research, to get into his bank account.
