I recieved my sim card on the 31 March 2020 and had to wait for successful activation, the next day my network was working, then off the next day until no I have done settings as per a helpful agent, today I requested a call back and a useless agent Itumeleng Letsapa was of no help just ended my chat whilst I was still speaking!!! Cancel and refund me immediately I did not pay R480 for nothing.
