Who called from 7702851842

Called our business, when I answered a flustered sounding woman was speaking to someone else.  I heard "no because you don't have...hello?" and disconnect.  Second time in as many days they have called.

Called again.  No sound at all before a disconnect.

She was very rude, wanted to speak to the owner, and I asked owner of what, she said she thought the owner was Mary, I said the owner of what, said she needed to speak to the owner, is she available or not, I asked the owner of what, she hung up

Nothing on the other line- I said "Hello" twice- they hung up

calls 2-4 times a day . No one is ever on the other end.
