Incorrect billing

<p>End of July I did an upgrade online and was told that no upgrade fee is payable. On my August statement I saw that I was invoiced R2 214.93 (K ********** ) for this upgrade. I phoned about 2 weeks ago to query this and was told that a credit note (CNI958157) R2 992.24 was passed for this. I spoke to a supervisor who confirmed that this credit note related to the incorrect invoice that was done with my upgrade. Today I was told that, the credit note was actually relating to a data query on ********** 408. I have been on the phone for over 2 hours being transferred from one department to the other to find out where the credit note then is for my upgrade. Everyone is telling me I'm in the wrong dept and then transferring me to another. This is unacceptable as my account shows it is in arrears which is affecting my credit rating. I would appreciate it if a manager could phone me back urgently to sort this mess out.</p>
