I have applied for KYC (Know your client) which is mandatory for purchasing of Mutual funds in June'2011 and submitted all documents along with address proof. Now when I tried to track the status of KYC it is prompting that invalid data. After consulting with CDSL Ventures they replied that reason for rejection is 'C/o address given as proof of address" which is not understandable. It seems that a person should possess own house to procure KYC. kindly look into the matter and solve my problem at the earliest.
