Bad first time contract holder experience

I done an online contract application with Telkom less than a month ago.Requested a dual sim Samsung A32 on a Top-up plan. Sales agent and confirmed. Receive it saw its a single sim took it immediately to Telkom Parow checked on system device is a dual sim. Days later when I wanted to use there's no space for another sim went back they can't assist me it was an online application up to day I wasn't assisted called countless times nothing .Decided just to port then, what was the last straw yesterday when I wanted recharge I couldn't just to find out I'm on a open plan of R1500 which way above my affordability a month. They don't want to change it back.

No one can assist less than a month with Telkom and my experience is horrible. Wouldn't advise anyone customer. I feel ****med
