Dena Bank — Not accepting fixed deposit amount without having S B Account

Address: Ahmedabad, Gujarat, 380008

I have the three F D with Maninagar Branch, Ahmadabad which are matured . These F D were issued before three years without having Any account i e S B or current account.
I want to continue these F D for further three years but was denied as i have to open the S B account and there after these F D will continue.
There is no such rule previously nor it is there in any other bank at present.
No such instruction pass by the Reserve Bank also.
How the Branch Officer can denied to continue the F D without opning the S B account.

Kindly Look Into and advise the Maninagar Branch, Ahmadabad to continue the F D without opening the S B account.

Thank you.
