Trai — kotak bank customer care

Hi..

I have kotak credit card... Very bad customer care service. They are not treating the customer properly. Asking rubbish questions.. Customer phone numbers are given to executives.. No confidentiality..
Executives text in wats app... I dont know is this the way reaching out to customers.
Getting irritated of this calls. They decrease the limit of credit card continuously and putting charges as overlimit. Need an immediate action..
