HDFC Bank — Without any prior information 531 has been charged

Hello team
Hdfc gave me such a bad experience. They deducted my 531₹ without any prior information. I did a transaction of ₹113 from my account in evening today and they deducted a amount of ₹531 in evening only. Just ₹5 was less from my minimum balance. I was shocked when I checked my amount it was 500 rupees less I had no idea I thought I will put back ₹5 in my account at night . Then I checked my bank statement . My account was having ₹9464 something. And googled it why it's happening. It was a shock for me like is this a joke or what. It's a hard earned money and they are deducting it like it's there. I want my money at any cost . Otherwise I will take next step.
