I mailed a payment on a bill from Pennsylvania to Texas on December 15. Today is December 28 and it still has not been received. Do you think it is lost? Or is it normal around holidays to take that long? It was late in the day on Thursday, Dec.15 and the 17, 18, 24, and 25 were weekend days. Should I be concerned? Check did not clear at bank and no notice of it pending to check funds either.
