State Bank Of India [SBI] — Educational loan closure

Address:	641601
Website:	onlinesbi.com

I had availed an educational loan for my son’s higher studies from “ state bank of india” – uthukuli road branch, tirupur – tamilnadu.
Received the loan amounts between aug’2008 & feb’2010.
The loan repayment period was between aug’2010 & july’2017.
I have been paying interest regularly during the study period & the repayment was also regular to quite a maximum extent.
Due to financial crisis in the family my repayment was irregular for a few months & payment remitted to the bank was little less than the stipulated emi. So the balance of emi (S) got accumulated.
During this period i used to get calls from the bank for the payment. I was prompt in answering their queries &
Never avoided their calls as i was liable to them.
During the month of feb’2017, i was served a letter from the bank stating the overdue pending.
I had assured them that i would settle the full sum liable to them in due course of time.
Now i have settled the full outstanding that was liable to the bank on[protected] & i have obtained a “loan clouser certificate” as well.
Even after settling the loan amount, i am getting frequent calls from the bank enquiring for the payment details.
I have clearly indicated them that i have settled the amount.
I have received calls on the following dates :
4-04-17, 8-04-17, 11-04-17, 21-04-17
Sms : 13-04-17, 18-04-17
In the mean time i visited my branch & complained about the calls & sms. I enquired them about how there was such a call. The deputy manager discussed something with his senior official & assured me that he will take it forward & see to that there would be no more such interventions.
I had also sent a mail through the banks customer care site for which i didn’t receive any response.
But again i received 2 call on 22-04-17 in the same bank number, which i couldn’t attend as i was travelling.
I have received a sms on 24-04-17 again stating that my loan account has become irregular due to non-payment of dues.

Kindly advice me on how to take this forward.
