ShareCare Faith in Action has not received mail this entire week. I am expecting a lot of mail!!!! We receive our mail through the Cathedral Church of the Nativity at 321 Wyandotte Street, Bethlehem PA . They report that they have not received mail either. A $10,000.00 dollar check from the City of Bethlehem has been compromised. We need our mail and it is obvious not being delivered.


I've had a packaged that has been out for delivery awaiting scan for over a month. A case was opened and nobody has contacted me. You don't answer the phone there any day of the week! Do your jobs
