Bank Of Baroda — back dated rent charged by bank of baroda on pos

Address: Bangalore, Karnataka, 560004

On 29/12/2017 i recieved a letter from bank of baroda stating that rental will be charged on pos. But also they mentioned that they will charge rent from may 2017 which is not fair on there part. As far as i know without intimation from may2017 they cannot charge. Please refund the amount from may2017 till dec2017.
