Yes you're right.

When your system consists of functions "A, B, C, D", I'd expect to see test suites for "A, B, C, D". In this case there were test suites for "A, B, C". The client found D therefore the test suite was incomplete.

Now if a bit of A, B, C or D suites were missing that would be different and entirely expected.
