Get your act together, please.

On the 03/05/2019, the SIM card on one of the 20GB packages stopped working (Last Usage Update 2019/05/03 21:25:1). I then brought the router and the SIM into your offices in Rivonia. One of your service consultants did a SIM swap. After 3 hours, that replacement SIM did not work either. II went back to your offices, again with the router and the replacement SIM. The service consultant then issues a new SIM (which was not treated as a SIM-swap)). That SIM works. The problem is; You have billed me for the faulty SIM which has not worked since Last Usage Update 2019/05/03 21:25:1. Your service consultant assured me that there would be no pbilling issues. Well, ,he was wrong. I am being billed for the faulty SIM which he confiscated. Now your Whatsapp Chat is a waste of time. Perhaps Thulanie N needs to go on training. If your stuff-up, please, rectify the billing issue and refund me. Maybe also reprimand the service consultant that caused this issue in the first place after assuring me that there would be no problems. Don't ask me for the serial number of the SIM that works. Look on our system. Don't ask me for the serial numbers of the SIMS that don't work. Look on your system.
