This is an Indian company who purchases lists of companies and bombards them with phone calls offering 'cheap number 1 technology solution'.

Just hang up on these idiots.

Yes, Indian company selling tech services. I suggest start speaking another language to them. Like you don't speak english. Make one up if need be.

How about you be kind and civil and just say you're not interested.

Me detect some racism here.

If it were a White company, would they be idiots?

How do you know he's white?   A little racist arent you?    Amazing,  awesome,  and racism are the most over used words today.
If you dont like it,  ignore it or just....[***] off.....

201-299-3668 called me every 5 minutes for 30 minutes .... I never answered.  They never left a message.   Says "Unknown" so I did not answer.
