So the next roll( same camera, same make of film and same lab) was perfect? If the answers to these questions are "Yes" then it would seem to point to something going wrong at that lab on that particular processing session.

If you are a regular customer and it values your business then if they don't think you are about to slap a big compensation claim on them you might get an honest response to the effect that something might have gone wrong.

Worth a try. You could rely on us coming up with the right answer but neither you nor we will ever know if we have got it right.
