Vodafone India — complaint on close postpaid connection

Address:

I have deactivated my postpaid number on Nov 3 2017 after paying all the standing amounts in Vodafone store. But still I am getting mails to pay for that number and mentioning that if not paid we will send leagal notice. This mail was came on Jan 2018 and again few days back. But when I went to Vodafone store they were telling there is no standing payments, so u no need to worry. Can any one please help.
