Kotak Mahindra Bank — Salary account

Address:

Mumbai City, Maharashtra, 400703

I had a salary account with kotak mahindra, then switched to another company, that company had salary account in hdfc, i had around 1500 rs balance in my kotak account, now these kotak guys converted my salary account into savings account without informing me and deducted whole 1500 in the name of low balance charges and my balance is now zero, there is not even uniformity in their charges, its 900 one month 600 for another month, how can such a company be like a theif all other banks inform before making it a savjng and inform abt low maintenance charges. I demand a complete roll back and a payout of the money, while coming to it company campuses they beg us to open accounts and dnt reveal these details
