Vodafone India — closure of m-pesa account

Address:

Vadodara, Gujarat, 390020

I have a vodafone telephone since more than a decade and an m-pesa account with rs 236 credit in my account.
When i opened the account, they said there is no charge. I did not use my account for many months as i changed my handset. I suddenly received an sms that they have debitted rs 59 from my account. This happened on 31st july 2017. Again they debitted rs 59 from my account on 30th nov 2017. When i called them and insisted that this be reversed, they did so. However, the earlier rs 59 is still not reversed.
I called them on 22nd dec 2017 on 55400 and spoke to one mr shubham to close my m-pesa account and transfer the balance to my vodafone telephone number against pending bill.. After asking for my personal details, he asked me for last transaction which i said was rs 59/-. He refused to accept this. He also refused to allow me to speak to his supervisor.
I really do not understand how they can forcibly deduct rs 59 and also not allow me to close the account? Their website faq also does not state how to close the m-pesa account.
Please help.
