In the world of business it is said that the customer is always right and here at UPS that seems to be no different judging from the amount of baffling complaints that seem to make their way back to our ears. Some are totally understandable but some just seem to come out of left field. Example: Customer calls to complain that the driver - me - did not knock on their door. That's right, I RANG THE DOORBELL. When the customer was informed of this, they proceeded to say that the doorbell did not work. Well, with no note to indicate this, how was I supposed to know? (Yeah, I know i could have knocked as well, but when I rang the doorbell a dog inside started barking so I assumed the doorbell worked) The other day a customer called to complain that I was delivering to the wrong apartment. The box said apt. 500 and the registry had the customer's name listed as apt. 500, so I buzzed that number. The customer called in a rage and said she moved to, i don't know, apt. 700 or something. Well, gee, if you didn't change your address with the shipper and your building super did not change the registry to reflect your move, how is that my fault? Oh but my favourite has to be this: I once got a complaint from a customer who called to complain that I was delivering to his house WHILE HE WAS AT WORK!!!! And since it was an Adult Sig. Req. package there was no way he was gonna get it. I mean, really, whoever takes these complaints and forwards them on . . . why would they think that this was even feasible? what are yours?
