credit not received as promised

We are still waiting for a credit that was relayed to us per telephone by your department regarding our previous report of 5 May.<br> We will not be paying an account of over R1,000 when we should be paying not more than R500 in any one month. The error has been admitted and needs to be credited.<br> A token amount was paid of R400 on May account until our all the overcharges from Dec 2014 until May have been credited.<br> Very bad service and will have to consider cancelling this service.
