EZ Cater Refuses to Pay Us

Anyone experiencing problems with receiving checks from EZ Cater? We are owed several checks from as far back as May25th 2022. We since switched over to ACH payments. My wife has talked with several people with NO satisfaction. I believe it was initially the Postal Service. But this length of time and asking to pay us by ACH for money owed to us is now falling on EZ Caters shoulder, and its like they don’t give a crap.
