Complaint regarding SIM card deactivation.

This problem is faced by BHUSHAN TATHED ,KETAN KANERE,AND myself.We had purchased the card from OM mobiles,Chandwad(Nashik).The numbers are 9860403076,9860400164 and 98604903331.These SIM cards worked properly for 6 months but suddenly a day arose and all the SIm cards were blocked saying that the documents were incomplete.I resubmitted the documents but still the didnot activate the card and today the card is ultimately out of service.WHOSE MISTAKE IS THIS?
