Kotak Mahindra Bank — complaining about arbitration letter received

Address:

560016

Hi, I'm from bangalore and I had a personal loan from kotak Mahindra. Only on March MOnth I missed to pay the EMI and paid two EMI's together in the month of April. However, I received a notice from the bank on April 18, 2018 asking me to repay the full amount in 3days. We visited the bank and confirmed that there is nothing to be worried and all is well as we hav paid the pending EMI's. However now after 15 days I have received a letter of arbitration from a layer stating that he has been appointed as arbitrator to settle the dispute.. Please advise how to deal with this and what is the Nxt step I should be taking and is there anything that I should worry about??
