2nd Complaint Lodged and still no customer response

I logged a complaint on the 9th of May. To date all I have received from Vodacom is an email from a generic email address ********** saying that they will attend to it. This is not acceptable as I have now received an invoice with the amount in question and seeing that they are treating me this way, I will just reverse my debit order. Seeing that they indicated that my contract only expires in June, they will then have to cancel my contract. Vodacom, your service really sucks!!! You can also collect your phone at the same time. Are you hoping by ignoring me I will just go away?
