I was surprised to get a call from them regarding a pharmaceutical bill from three years ago! Turns out that they were trying to get it in under the state deadline for billing which would have expired in a month. The operator was courteous and provided me with more information than the pharmacist did. After going back and speaking to the pharmacist it turned out that the pharmaceutical company was the culprit since they were at fault due to their new computer updates from 3 years ago creating a new account for me and not transferring the old bill to the new account. Ridiculous, but not the fault of the creditor.
