Caller said he represented "merchant services".  Asked if my business took credit cards.  I responded "no".  Caller asked rudely "WHY NOT"?!  I said please put me on a do not call list.  Caller hung up immediately.

Listened nicely to the credit card services pitch. Told them absolutely no interest.  They just kept on talking.  Finally said, I've been nice, appreciate you are just doing your job, but now you are wasting my time.  Put his manager on.  I hung up and promptly blocked.  1/2 of my calls everyday is dealing with robo or sales calls.  I am on DNC list.  But that doesn't seem to matter.

Unfortunately, the DNC list does not apply to businesses, only home phones.

I keep getting calls on my personal cell asking for a business. I inform they have the wrong number and they don't care. I am on the DNC list.
