"Hi, this is Rob with Customer Service - How are you today?" - Great Rob - what do you need?
"I'm calling today because we are preparing to send out an 'updated operating manual' for your printer and I just need to verify the make and model number so that we are sure to send you the right one." - Rob - if your call is legit; you should have all those details within our client file.
"We do - but our server is 'down at the moment', so I was hoping you could just check this for me so that I can get this in the mail to you today." - Rob - if this were a legit call, you would know that we RENT all copiers and therefore, the operator's manuals are hanging on the back of the machines and you would know that we don't want your toners... CLICK!
Good ole Rob - he calls every 21 days.  Dude - you will never get it through your thick head... I don't want your cheap-a$$ toners that were made overseas, just so you can charge me for a whole pallet of your crap-toners and demand an outrageous payment down the road because you were supposedly given a verbal authorization over the phone.
Get a life you waste of space!
