Based on the above agreement, I paid first installment on[protected] and ready to pay other installment on time. Meanwhile, I have transferred Rs, 91000 to my kotak mahindra bank account to pay PEROSNAL loan emi's. To my surprise, kotak mahindra blocked my entire money and not allowing to pay emi. I got to know that, the amount was blocked from credit card department. I called customer care executive to unblock my account, but there is no proper response. They asked me to pay extra amount to unblock the account, I explained that I don't have money on other account, so can't pay it. I requested customer care to allow me pay from my blocked account or requested bank itself take action and auto debit it. But the customer care executive not agreed, I spoke to senior manager, collection department, collection agent etc
None of them giving proper response, they are not taking any action... The recent update from collection department is that it might take one month to unlock my account. When i asked why Rs. 91000 blocked for around rs. 50000 outstanding amount, no response. Whenever I talk kotak mahindra agent or customer care, they say it is pending from department x, y, z ( some internal department). I don't see any improvement. Finally, the agent told me that it might take 15days to 1 month to unlock my account.As a customer when I delay payment for a day, the kotak mahindra bank put so many charges( late payment, over limit, financial charges, interest charges, gst charges, card processing charges etc) and steal my money from bank. But when there is unreasonable delay from kotak mahindra bank, they are speechless, no response, max sorry from them. The kind of process they follow is daylight robbery from customer, I need strict action against kotak mahindra bank and kotak mahindra bank must be fined for difficulties causing to customers. Also, I need immediate response for my problem and componsation for putting me so much trouble, causing mental and psychological problems.
