HDFC Bank — Mirevenue hold

My account shows a negative balance of 5800 mentioned as mirevenuehold. It happened last month also they kept 3000 as hold and i didn't get the money. I got a salary of 5000 of which they kept 3000 as hold. Due to this lockdown situation its very hard to survive and this bank does such injustice to customers. I tried reaching customer support but it works only for blocked card. This month i'm yet tull o get half month pay but already its 5000 negative how will i survive. I seriously want to escalate the issue
