We get multiple deliveries a week via UPS. Last month , somehow they managed to loose not 1 but 2 checks that we gave them for COD deliveries. One was 400 something dollars and the other one 300 something. They called and said they need me to replace them as they have record of me paying at time of delivery, but it was lost after the driver turned them into the dispatch. ... Problem is, I write checks out of anywhere between 8-10 books and do not record them in a register... I have no way of knowing the check numbers and my bank won't do a stop payment with out one... Any one had a similar experience ? What did you do ?
