Poor customer service from clicks after bill payments made not reflecting on their side!

On the 27 May, I paid my municipal and Eskom bills using EasyPay on the Clicks website. On 5 June, I got a pre-termination letter from City of Joburg because my account has not been paid. I have proof on my FNB account that I paid. The customer support was not very helpful, just stating that the payment is not reflecting on their side...what pathetic response! It is not the customer responsibility to sort out YOUR issues... checking the other posts on HelloPeter it seems like there is a bigger issue with the Clicks payment system, since a number of other customers complained about the same issue! Why are you not doing something to sort this out, instead of telling customers that the payment does not reflect!!!
