Pathetic Call center

Been calling multiple times to try to get hold one of the agents to assist me in upgrading my current service . To no avail , I’ve purchased over R500 prepaid airtime to call the call center over a period of three days straight and waiting on the call the entire day for no one to answer and my money wasted on airtime. Also , every month I pay for my WiFi and Telkom puts it off after I have paid. Never have been credited for the inconvenience. My cell phone account was upgraded to another service without my permission , my bill is sky and when disputed , Telkom never ever responded. Pathetic company , pathetic service delivery , theft . Telkom is just **** .
