Vodafone And Idea - wrong bill fake promises and plan updated by own

On *th sep. **** i had decided to port my number in jio so i requested my number porting in jio network. I got port no from vodafone and i had submitted my documents in jio store for porting my number. now i got a call from customer care of vi (vodafone and idea) in the evening around * pm. and the lady (neelam) talked to me and introduce herself as a senior executive in vodafone. she said to me don't port your number in jio i will give you better plan if you cancel your port request, i said i already submitted my documents and money for porting my number but she said i will update your plan in *** monthly rental in which you will enjoy unlimited call in india, ** gb data, roaming free, vi app and zee* app free and you no need to pay your bill for * month also. i asked is it true. she replied yes and i am going to submit that plan application right now and plan will be activate in ** hours but have to cancel your port right now. i said ok i do than i share my port cancel request id with her she updated in her system and my port has been cancel at that time and she said save my that number ********** call me when you go to jio store, i will refund your amount which is already paid by you for porting your number in jio...... i said ok and than my porting request canceled..... i waited till **th sep. ****.
no plan updated as her promise and she didn't pick my call i tried so many times but she text me plz call me back later or please text me here. so i called vi costumer care and talked but they told it will be update asap.
finally on **th sep ****. i requested again for porting my number in jio.
all the documents and again porting fee submitted by me than i got a call in evening again they said don't port your number i will updated your plan in *** per month but i said last time you guys already promised a fake commitment so i will never trust on you..than without my permission they updated my plan by own and generate a bill of *** rs. I said correct my bill i will never pay this because its a fake one but they don't consider this and said to me pay the bill otherwise we will banned your number. Now on ** sep. **** i visited vi store in navyug market ghaziabad. care person told me we can't help you. you have to pay otherwise complaint on email id
