Peco received two different checks, from two different people in the same envelope to pay for a bill. One check was cashed by them, and the other was not. They are requiring a copy of the canceled check to show payment; however, obviously there can be no copy of the canceled check because the check was never received by the bank in order to cash it. So what the heck happened to the other check? It was in the same envelope as the one that WAS cashed! They refuse to admit that they lost it. How am I supposed to show a canceled check if I don't have it????? read full review »
