Vodafone India — non-closure of my postpaid number

My customer relationship no. With you is[protected]. I had applied for the closure of my postpaid no. [protected] on 11-jul-2017 at your mng-pune-chinchwad outlet. You customer care executive contacted me on 12-jul-2017 asking the reason for the closure of aforesaid number and asked me to email a confirmation mail and then the process would be over. I mailed him accordingly. But, to my amazement your customer care representatives are still asking me to pay dues as my no. [protected] is still "active". It is to be noted that i have already paid the entire dues (Rs.457/- as told by your customer care executive at mng-pune-chinchwad), the receipt no. Being mhg022r170711_37116170, dated 11.07.2017 and communicated to your representative through an email as well. I am much harassed and request you for the final time to close the number and stop harassing me. I am enclosing herewith the email correspondences on the issue.
