How to utilize "COUNTIFS" to return a count of unique values

[ascottbag-hcm]

In the example below I need to return a count of column "B" data "Garcia,
Deborah", "HARRIS, CHARMAINE", "SEIBLY, RONALD" only where the data in column
"A" is unique to the same data in column "B". (Repetative values in column
"A" being counted only once per data in column "B". I need the below example
to return a count of 2 each for "Garcia, Deborah", "HARRIS, CHARMAINE" and
""SEIBLY, RONALD". Complicating this calculation is the fact that two of the
agents in column "B" touched the same contact in column "A", note the same
contact_ID.

Is this possible?

With data from A2 to C10 with no blank rows try the below formula...You can
reference the name to a cell..Please note that this is an array formula. You
create array formulas in the same way that you create other formulas, except
you press CTRL+SHIFT+ENTER to enter the formula. If successful in 'Formula
Bar' you can notice the curly braces at both ends like "{=<formula>}"

=SUM(N(FREQUENCY(IF((B2:B10="Garcia,
deborah"),MATCH(A2:A10,A2:A10,)),MATCH(A2:A10,A2:A10,))>0))
