Vodafone India — postpaid to prepaid change in my two numbers

Address:

395010

I have given application to convert my two vodafone postpaid connection to prepaid connection along with necessary kyc and photos at vodafone ministore jetpur (Rajkot) on[protected]. And i have paid the due amount on[protected] as per their instruction.
Rather than converting my numbers into prepaid connection, they have changed the plan in postpaid only in both the numbers. I have complaints at nodal desk 3 to 4 times (Date[protected] time 12.20pm vodafone nodal officer mr. Amit, date[protected] time 12.46pm vodafone nodal officer mr. Bhagirath, today[protected] time 12.18pm nodal officer mr. Chirag)
But they are not listening anything apart from extra money for new changed postpaid plan which i have never requested.

I have never requested to change postpaid plan and now they are asking for extra money for that.

My number are [protected] and [protected]
