State Bank Of India [SBI] — complaint regarding home loan a/c no : [protected]

Address:

380007

Dear Sir,

I am tying to change my Home loan interest rate since Jun 11 2017 to SBI on different Email address. Also Visited SBI branch 3 times for the same during this period.

I tried to calls several times to Manager Mahipal. Finally he changed on 05th Aug 2017.
They lost my request application from and Cheque which i submitted to branch also.(Are they serious to keep documents secure?)

Now from 05.08.2017 my Home loan Interest is 8.60% as per information given by him on my branch visit - 14.08.2017(Attached given)

Now when I asked him to share history of rate of interest he gave me document(As Attached) which is as below :
Sr. No. Date of Change Rate of Interest applicable
1 17/04/2010 8.0000
2 17/07/2010 8.0000
3 17/04/2011 8.5000
4 17/04/2013 11.7000
5 19/09/2013 11.8000
6 7/11/2013 12.0000
7 18/06/2014 10.1500
8 10/4/2015 10.0000
9 5/8/2017 8.6000

Now my queries are as below:

1.) I have been trying to contact bank through email since more than years or rate of interest - what they are charging / what is applicable but they never reverted with full information.
2.) During these years they have changes 8 times my rate of interested but this time only they have asked for some money to change rate of interest and request form - why this time?
3.) When in your document said that since 10th April 2015 my rate of interest is 10.0000% than interest certificate which I received for FY[protected] is showing 9.40%(As Attached). So why both documents which i received from bank differ with each other? which is correct and which is in correct?
4.) Why every year I need to send several reminders to send me interest certificate?
5.) If they required Request application form and cheque to change rate of interest(Switch over) than why they change it on 05/0/2017 without my concern?
6.) Where they lost my cheque and application from which i submitted?
7.) They are advertising that interest rate for Home Loan is 8.35% or below than my rate of interest is applicable 8.60% - Why I should pay more?
8.) Initially when i taken HL - they forced me to buy credit card(which they forcefully gave) and Insurance(Forcefully inbuilt with loan - which i cancelled after disbursement)
9.) How much time bank will cheat us?
10.) Request you to check all financial statements of my home Loan and share details how much your charges more interest rate to me - why and when will you refund my all money with interest?

Request to revert proper responds for each my queries at priority else will go to court.

Regards,
Jay Shah
