To be honest, it frightens me that people with so little experience become Dive Masters. A friends ex-wife became a DM. She went directly from OW, to Advanced, to Rescue, to taking her DM course. This with NO OTHER DIVES. The dive shop told her they would make sure she had enough dives on her log to make it legal.
If you know this for sure, you should report it to the agency. If you are talking about PADI, you cannot start a DM program with that many dives, and you have to have many more than that before you complete the program. What you describe is a standards violation.
