Zero Accountability

Carrier misdelivered a check of ours early last week. Have been to the post office daily to speak to the route supervisor and they are either unavailable or in the field. Left our number multiple times with the clerk and they never call us back. Filed a missing mail online and no follow up from the USPS. There is zero accountability for anything. Now we have to wait ten business days for the sender to do a stop payment but in order to do so we have to get a form notarized for them and our bills will be paid late with late fees. The stupid carrier messed up and the only one who has to deal with the aftermath is us. So freaking frustrating.
