Still being billed for a phone that I shouldn't be, credit for previous invoice mistake still not paid back

<p>I refer to my previously loaded hellopeter review: </p> <p>https://www.hellopeter.com/vodacom/reviews/billed-for-phone-that-is-no-longer-used-after-upgrade- ********** </p> <p> </p> <p>I was told by a hellopeter advisor that I will be credited the amount for the phone that I shouldn't be billed for. This was on 4th July and I still have not received said credit.</p> <p> </p> <p>Received my invoice for July and I'm once again being billed for the phone that I shouldn't be.</p> <p> </p> <p>So not only have I not received my money back from last month, at the end of this month I'm going to pay double again.</p> <p> </p> <p>Please can you sort this out ASAP, credit the amount that I was told was going to be credited and fix the invoice for July so that I don't once again pay for the phone that I shoulnd't be paying for.</p>
