Convert from pcc to ipcc

I was a student of PCC and i converted to IPCC as per the guidelines of ICAI.

But till date I have not received the letter of conversion.

Can someone guide me what to do in this case?

I have tried to call the "Western India Regional Council of The Institute of Chartered Accountant of India" ICAI Bhawan, 27, Cuffe Parade Post Box No. 6081,Colaba, Mumbai on this Telephone no. of CA Institute   022-39893989  .

But no one is replying/receiving the call.

Pl. help on urgent bases. I want to apply for this Nov 13 exam.

Thanks!
