Horrible when an employee of kelseyville post office can work with people who steal mail(checks) alter and cash at the kelseyville post office. Sheriff of lake county thinks employee # 63 is part of the mail theft ring up along 101 corridor. Postmaster won’t reimburse for an altered usps money order and cashed by this employee. Don’t bother with usps money orders. You can’t get reimbursement even though the rule is no change on pay to line but employee 63 cashed for a boyfriend/lover at drug and theft town kelseyville ca. go USPS.
