Vodacom account that is not mine being charged to my account and money debited

<p>Please can someone urgently rectify this situation. My mom has moved over to Vodacom and taken out a new contract. Some how you have managed to mix up our details and use my banking details for her contract even though she provided you with 3 months bank statements with her account details. My mom has had to spend her time trying to sort this out through your error that you still cant explain how this has happened? On top of this you debited my account causing it to go into arrears and therefore I was charged R75 bank charges that you need to refund me . This problem was supposed to be sorted out on Wednesday and no one has bothered to come back to my mom . Shocking service </p>
