Sim Block by Vodafone India

Sirs,
I am a Post Graduate student in IIIT – B, at Bangalore and I have been using prepaid of Vodafone since 2005. Yesterday my SIM having mobile no. 99861 61567 was blocked though I submitted their requirements two months back at Vodafone Center on Banneragatta Road, B’lore as per their advices. Really it surprised me to block my SIM without any reasons or prior notice to me. When I approached the center who collected my details could not give the reason for blocking my SIM and also stated that it would take 15 days to resume my number. But when I lost my SIM alongwith my mobile three years back, I could able to resume the same number with in three days. So why not now.
Now I am getting calls to attend interviews. At this juncture the blocking of SIM is affecting my career. Hence kindly look into it and see that my SIM be resumed immediately. As an emergency I took the temporary SIM bearing Mobile No. 9742864258.Your early action is highly appreciable in this regard.

Regards..
