ACS -- Academy Collection Services.
Called looking for husband's ex-wife.
Told them last year to stop calling as she didn't live here, never had and would never and that we weren't responsible for her bills.

ACS - I believe academy collection services - they have a bunch of phone #'s -

Called my cell phone, which I never give out.  I tried to call back, but got a recorded message that my call could not be completed. Pretty sure not a debt collector, as we have no outstanding debts.  Anyone know this number?
