Idea Cellular — bill generated for non-active number

Address:

Pune, Maharashtra

I'm holding idea corporate plan and Long back ( in Aug 2013) I'd requested for another idea number, I got the SIM also, but that number never get verified and hence remain unactivated. Today I got a call from Delhi Court that case has been filed on my name for non payment of INR:1350. The number ([protected]) which they have mentioned was not used by me at all. When I called Idea customer care, representative Informed me that the numbed against which case is filed is registered on my name, even it has my company address also. According to him the no was in active state and deactivated completey as no bills paid for that number. Surprisingly I never get the bill soft/hard copy. I am still wondering how the bill is generated for non-active number.
