I had a woman call me at work, and this is how the conversation went:
Caller: Hello. This is Judy calling from your copier's customer service. I just need to get the serial number of your ImageRunner copier.
Me: (knowing she was going to try to sell me toner or just send one and bill us, I replied) We don't have an ImageRunner. (which we don't)
Caller: Yes, you do.
Me: No, we don't. We only have one copy machine here, and it is NOT an ImageRunner.
Caller: [getting mad] Uh, YES you do. If it's not an ImageRunner, what is it then?
Me: I don't know; it's in the other room. You know what? Let me go check......it's a Canon.
Caller: *scoff* Well that IS an ImageRunner.
Me: What is this in regards to?
Caller: [rude] I'm just calling to get the serial number. This is customer service.
Me: We don't have a sticker on the front. We do all of our customer service through another company.
Caller: This has nothing to do with that. [getting condescending] Right on the front where it says CANON IMAGERUNNER, it has the serial number. Starts with 224 and goes from there? I need that.
Me: What is this in regards to? We DO NOT have an ImageRunner nor a serial number sticker on the front of our copy machine.
Caller: It IS an ImageRunner *she hangs up*
Right............."your copier's customer service." Damn, I wish I had been quick-thinking and said, "Damn! I didn't know my copy machine had its own customer service network working for it!"
