Kotak Mahindra Bank — Not helping me to transfer my ecs to other bank

Address:

Faridabad, Haryana, 121005

I have written so many emails to kotak for transfer of my PL to HDFC bank but they are not responding to it . They are just asking for bank statement again again which I already did. I even once visited to their office in CP and Vaishali enclave and submited all the docs but still no response. I am being harrased. Please help.
