Axis Bank — wrongly blocked amount for ipo

Hi,
I have tried to apply ipo with axis bank. When i tried to apply that time got error message then tried couple of times. All the time got error message. But yesterday when i check axis bank they blocked amount for applications and 4 times failed. I have tried withdraw from online but unable to do. I called customer care they told me to wait for 7 days and telling they have problem with their server and lot of customer are facing same issue. It is not acceptable answer. If we apply multiple ipos sebi will reject all applications. How to file a case on axis for blocking my amount and also keeping my amount for those many days.
