Barclays closed my mother’s bank accounts because they thought she had died. It was a “clerical error” ie someone had received a death certificate and processed it with about as much rigour as a 2 year old could muster. They sorted it within 5 days though and paid out compensation and sent her a hamper as an apology. Hopefully they fired the moron who kicked off the process too. At the end of the day this shit happen…
As you say things happens, so who are you going to fire? It mostly is just a bad coincidences that make these things happens, it mostly is not the guy committing the error who is at fault. I do not want to live in a society where you treat the administrative clerks like you imply.
