Vodacom new cellphone number *****

Debited two amounts simultaneously on a new cellphone deal.i took the phones three days ago and the sales person only notified that the next step is to authorise a Debi check on my Capitec app.i haven't authorised any debit order yet but already they deducted two separate amounts yesterday on a new deal that is 3 days old.i need the refund and will be taking back the phones and cancel the deal.i was assisted at Vodacom Mall of Africa.i suspect *****ulent activities here.the amount is more than R800 and already we have paid R200 for simcards in store upon collection.
