TERRIBLE, DISRESPECTFUL AND PUTRID SERVICE

I ordered a new Telkom 50gig wireless Modem with sim . It was only activated Wed 18 Aug 2021 - Logged onto my portal - It didnt show the usage and reflected 40gig Today - I cancelled it as i called in twice for tech support as 23Gigs later Data was depleted - and I was told on both Occasions someone would call me back, The first agent Desmond promised this (no call received from 15:00pm to 16:25pm) - and the second agent (called back at 16:20) who didn't introduce Himself , seemed occupied with whatever else was short of, sounded like he was not at his station and I could distinctly hear he was in the open with all the car sounds driving past and people talking - better yet also told me someone would called to this hour 00:47 - STILL NO DAMN CALL
