Airtel
Suddenly outgoing calls were discontinued

I have done the MNP from BSNL to Airtel (94482 40601) around 6 months ago. Incoming/Outgoing calls were working well untill yesterday night. Suddenly my outgoing calls were discontinued. Whatever the number i try to call it goes to 121 customer support, also the customer support representative. They were telling that my outgoin were discontinued due to the security verification failed. If i call by my mobile either me or the customer support representative couldn't hear the voice. Howcome past 6 months nothing happened and suddenly they discontinued my outgoing call telling the security reason? Even airtel didn't try to call me for verification. They do call me only for marketing purpose.
