Clicks Online App not reflecting my payment

I recently made an online payment for my household RATES using the Clicks online APP , the so called safe convenient way to make your life easier . I made the payment on the 29 MAY and to date there is no reflection of the payment on the clicks profile under history or with the Rates department . The monies however as been deducted from my cheque account . I called clicks as there is no complaints line and also emailed *** with no response . The clicks call centre was fully aware that there are other customers with the same issue of bill payments not reflecting. Why have I received no response . Now I am in arrears and the City of Joburg is known to cut your lights for non payment.Terrible after service from CLICKS , you are aware of your online issues yet you stall and do not assist a customer .
