Very disappointed Vodacom customer

Good morning, I am really disappointed in the level of service from Vodacom. 2 Months ago we upgraded a contract. After the first month's debit order we went back to the store as the amount was not right. They realised that they loaded an incorrect package with the phone. After an hour in store, they promised to fix the problem. I am still waiting on someone from Vodacom to tell me the problem has been sorted. At the end of June my debit order went off and they deducted the full amount for the handset. I've been in store, they escalated it to the contact centre. I've sent numerous e-mails as I really need my money to be refunded. They just do not care that they emptied my bank account. It's been a week now. Can someone please assist me in getting my money back. (1- ********** ********** ***~ZTGU)
