Indian Male--- Annoying caller, hang-up on the *(&#*%*(*(hole...

Male with Indian accent calling from 212-545-4121 asking for different employees in our IT Dept. Claims to be Alex from Symentics.  Has called three times in the last seven minutes.  He has been asked to stop calling. Has called two more times in the last five minuets.  Will not stop!!   Called twice more as I am typing this.  My instructions from the IT Dept. is to hang up on him if he will not stop calling.
How annoying these people are!!!

Caller with heavy accent asked to speak to someone in our IT department regarding a promotion.  Sounds like telemarketing crap.

Calls and doesn't leave voice message.  Next time, I will ask him for his home telephone number so I can call him later in the evening when I'm not so busy at work...this should really confuse him.

James (with an Indian accent) from "B2B" (though my CID showed AeroBeep) asked specifically for the CEO, when told he wasn't available, the COO, when told she wasn't available, the last name on his list was our Global Sales. At which point I asked what B2B does and he hung up on me! I guess he didn't like that question. Hopefully that is enough to get him to take us off his list.
