Pathetic Customer Service: License Renewal Disk

I processed my 3 motor vehicles license disk on www.paycity.co.za 2 weeks after processing payment and also paying a service fee of R99.00 for each vehicle they sent me an email saying that I need to pay an additional payment. Which if added up together roughly amounts to R200.00. I have been in correspondence from Danealle Peterson who has promised countless feedback for more than a week now and yet no feedback is given. Extremely disappointed in the customer service rendered. I doubt I will ever use their online service again. Extremely taxing having to continuously followup on their duties.
