Vodafone India — vodafone m-pesa

I want to close my m-pesa account. I didn't made the account. Someone used or hacked my mobile to create the account. He is using the account. I don't know who is using the account. Am getting texts about all the transactions. If my account will not be deactivated vodafone will be responsible for everything. As i mailed you request to close this account immediately. I can provide you my identification proofs if needed. I just want to deactivate this account immediately. [protected]@gmail.com
