We have had a VERY disturbing incident happen here in our shop late yesterday. During our regular afternoon pickup our regular driver has a supervisor shadowing him (something about the new board computer system they have put out this week) and he took it upon himself to approach one of our very good customers telling him he didn't need us and then badgering him into getting his own UPS account. This occurred inside our store less than 20 feet from where I was working with another customer. I have witnesses (they are currently writing up statements for us) including the customer he was going after. Reed was told several times by my customer he wasn't interested and he was even told specifically to stop because my customer told him "better watch it or She will rip you up" and he still wanted to continue his harassment. I was with customers and trying to behave professionally, unlike the UPS Operations Supervisor. When I had a moment I walked over to him and told him that his behavior was unacceptable and he tried to play dumb. This even infuriated me more because it was more than obvious that he knew exactly what he was doing. I am still currently awaiting a call from his supervisor from my call to UPS last night after he left. I know that a large number of stores like mine have had problems in the past with the various carriers and situations similar to this. Has anyone ever gotten anywhere filing a formal complaint or anything along these lines? Perhaps someone would have another suggestion or idea for us in handling this situation. We are gathering all of our statements and documentation and are planning to file a formal complaint with UPS. All your thoughts, ideas and information would be greatly appreciated.
