State Bank Of Travancore — no response/ bad behaviour

Address:

Thiruvananthapuram, Kerala

I am working in uae since 17 years and doing business with sbt for the same, i tried to contact several times to the bank through phone to know the balance in my account and nobody answering it. I am not receiving any messages when i send money to my account recently. I tried to send my pan card copy through email to link my accounts and no acknowledgement from the bank. I wonder if it doesn't reach to them. Kindly provide the latest email address if this wrong. (I chose [protected]@sbt.co.in as mentioned on the website)
Kindly update the email address in the website if any changes made from the above mentioned.

Thanks and regards
