Cant sort my account out

I paid my Vodacom account on the 4th of November when it was due - however I did miss a digit out on my reference number I email my deposit slip through 5 times but nobody has come back to me so I repaid the account so they could unblock my phone but I want them to trace my first payment as I have been now branded a bad payer. which will adversely affect my credit record. I have sent 8 emails to various departments pleading for a supervisors number so I can sort this mess out and have me removed as a bad payer as I did pay it just an incorrect ref number which I am sure they can still trace - all I want is for someone to say I will sort it out or it cant be sorted out or something but I need my name cleared as I phone in on 082111 on the 4th of November at 08:42am and spoke to a consultant and she gave me Vodacom's standard bank account in which to pay the money every one is now ignoring me and not coming up with a solution - it irritates me that somebody in a tiny cubicle somewhere has the power to mark me as a bad payer instead of investigating where my initial deposit went to of R2600.00 it is a lot of money and it has not come back in to my bank account so where is it
