Who called from 8476311699

The call has a terrible connection, says they are calling from india? They are calling a business.  When you call the number back it is continually busy.  Calls several times a day, unable to hear them.

Received call today from this number - showed Private Caller, but listed phone number.  Person asked for Jill Frill (?), spelled the name, and then asked if I was 'Karen' when I told them it was a wrong number.

I do not wish to receive phone calls from this number
