Citibank — Money deducted suddenly from my savings to Ready credit t and made my savings account empty

Address:

MG Road, Bangalore

I am Citibank Salary account holder for last 17 years. Yesterday on 17th October Citibank did a maintenance and deducted 22000 that was in my savings towards ready Credit. I called customer care and they said that I did not get salary in my citibank for last 45 days so they reduced my ready credit line and made an adjustment with the money in savings for the extra amount that I utilized. This is a harassments as I am receiving salary in my citibank for last 17years. The last salary I received was on 30th September.
The 2nd explanation was given that I am receiving my salary through NEFT which is again not new. I am receiving it as NEFT from IBM and now kyndryl as NEFT for last 9 years. Citibank did not even issue any intimation to me about this matter. I realized when used my card to purchase something in an outlet. How can Citibank take away the money from my savings without any intimation to pay and how did they decide suddenly that I am not getting salary in the account when each month I am getting it there.
The Principal and Interest towards ready credit was already dedcucted on 1st October. The customer care team said a supervisor will call me, but no call back was made. I need my savings money back in salary account, ready credit line reinstated and apology from citibank. Else I want to be compensated adequately for this harassments that citibank has subjected me to without any prior information that they want details on my salary.
