You have to approach the concerned SCSB for any complaints regarding your ASBA applications. SCSB is required to give reply within 15 days. In case, you are not satisfied, you may write to SEBI thereafter at the following address: Investor Grievance Cell, Office of Investor Assistance and Education, Securities and Exchange Board of India, Plot No.C4-A, 'G' Block, Bandra Kurla Complex, Bandra(East), Mumbai: 400051

Ideally, such issues can be sorted out between your bidding broker and your SCSB and any escalation must only be done as a last resort.
