Debit order issue

<p>I recently had VOX fibre installed and recieved the first months bill inc installation of R2,763.32, which I imediatly paid 27/07/2017. VOX then debited my account for exactly the same amount on 27/07/2017. I phoned VOX account department and was told they acknowledge the error and that I should go to my bank to reverse the debit order, and all would be in order. I went to the bank and reversed the debit order. On 31/07/2017 VOX then attempted to debit the same amount again R2,763.32! This was rejected by the bank. VOX then added a rejection fee to my account of R35. On 01/08/2017 I spoke to Arnold Settler at VOX accounts who said he could see the issue and would send a request to the credit department to have the charge reversed. Today is 07/08/2017 the charge is still on my account.</p>
