HDFC Bank — Unethical behaviour-no rip off

account No. [protected]oo
Unethical behaviour in customer dealing.Travelling India I decided to renew my fixed deposit at HDFC branch Ramphal chok sec.7 Dwarka, New Delhi. Mr Manager had no time to attend me, receptionist told me come three days before maturity date. She told me that it will be renewed on old interest rates. On 3rd Jan 16 I was told interest rates will be 8.25%. I have received now FD rate on much lower rates.There has been no acceptance to my complaint by their webside
There seems to be serious issues with customer services, disappointing with clients dealings, I may never visit this branch ever again.
Thanks
