State Bank Of India [SBI] — account closure request has not been responded

Address:	Thiruvananthapuram, Kerala
Website:	Sbi technopark

I have my savings account in sbi technopark trivendrum kerala. I created it during my training period in company. As i am not a resident of kerala i applied for account closure through mail on bank email id. As per commited by bank manager during account opening.
But they are not responding to mail.
Also the land line number they have provided at site is not giving response even no one is peaking the phone.
In internet banking the account is showing inoperative. I have some amount in this account.
Its been difficult for me to go kerala for this situation. I have raised the concern at online sbi customer service but even they have closed the complaint without any resolution.
