Indusind Bank — Over limit fee charged after moratorium

My Credit card limit is 38000. During moratorium period i have applied for moratorium and i have not paid minumum dues till august 31st. later after 31st august they started generating the bill with all charges with out late payment fee but with over limit fee. after this there was a huge pressure to me for making minimum due before my last date of payment. When i asked the reason they said over utilized. Which I have not done from my side. due to their huge pressure i have made minimum due along with over limit fee for august and september month before due date. Now again in Oct month bill generation again over limit fee is added due to which again it has crossed the limit. When i called customer care for a querry, they are telling some idiotic answer like only late payment fee will be waved off due to moratorium that too only august. after over limit fee is applicable as per conditions. Even for August and sep 20 i paid minimum due along with over limit fee thinking that it has come below the limit. But for Oct month also they are giving an idiotic answer. Where as when we minus the over limit fee in october month bill it was below the credit limit.
