State Bank Of India [SBI] — home loan closure

Address: 560018

I had take home loan from sbi bangalore chamrajpet branch office, i have been paying the emis on time, i have asked for preclosure of my home loan and transferred all the outstanding balance. I am in us and i have been constantly in touch with branch manager sripad on this and i asked him to give me the time to collect the homeloan docs, the day when i arrived to the branch he said the request is in service desk queue and they cant do anything on this.
I came to india only to get all the final settlement done but with such an irresponsible branch i am still in touch with manager to get it rectified, its been 1 month now since i am following up on this via email (Sbi.[protected]@sbi.co.in) and phone but nobody responds. When i see the bank statement they have again added interest on the remaining balance when there wasnt anything pending, it is sbi mistake that they are not able to close the home loan and instead charging me.
I regret that i took home loan from this branch and i would not recommend anyone to take any loan from this branch.
