Vodacom consultant's incompetence

I app**** for a contract online, the device that was sent to delivery was not the correct device so I canceled prior to delivery being scheduled. You people have debited my account for delivery charges and have attempted debit on my account again and have listed the contracted on my credit profile, I need my refund and need my credit profile cleared immediately, I cannot deal with the incompetence of your consultants. Have this resolved immediately
