Hi Reza,
Please note that an investor is eligible to receive the Consolidated Account Statement (CAS) provided he/she is having Mutual Funds (MF) investments in the Statement of Account (SOA) form and securities held in demat form with the Depositories. Further, If there is any transaction in any of the demat accounts of the investor or in any of his mutual fund folios, then CAS shall be sent to that investor on a monthly basis. However, in case if there is no transaction in any of the MF and Demat accounts for a particular month in a year, the CAS withholding details will be sent to the investor on half yearly basis.
Also, you should make sure that the CAS flag should be enabled in your demat account. Please raise a ticket in our support portal the concerned person will get back to you on this.
