struggling with telkom,regret day I stepped there

I took a contract with telkom at secunda for 5 gig any 15 gig night and 10 gig hotspots and they gave me wrong contract, I went there the following day and they said sorry we will fix it and they give me a different sim for the 5 gig package and told me they will fix everything on the system, not knowing that fixing thing in their minds is making my life worse and busy, since then they debit me for two contracts and I only get to use only 5gig the other 25 gig they said l have to call call centre to know how it works, Its a R219 payment pm and an hour ago there just took something like R740 just now, I hate telkom and I need them to be punished for this, go to secunda branch ask anyone there any easy question you can think of regarding ur laptop or phone, e.g how to reboot ur phone or how to use a phone as a modem they dont know, they just say call our call centre, I will do something I will regret I promise, not cause of the money but for them to know how ****ed I am, for them to stop playing games with people's money, time and emotions
