***** on my account and they charge me

A contract was opened in my name and linked to my Vodacom account. I saw it on my app on Friday last week. I reported it straight away and told them to freeze the account. First thing on Monday morning i emailed the required documents (affirdavid) through to the ***** department. Today, 6 days after reporting it Vodacom put a stop order through and charge me for this account! On calling the accounts department, i am told that it will take up to 2 weeks to sort it out and refund me. So i must pay because Vodacom let someone open an account in my name without the proper procedures being followed. I didnt even get an sms informing me that a new contact had been opened and linked to my number!!!
