Worst mistake ever

I regret the day I ever took up a contract with telkom as it was the worst mistake ever... not only is the signal ( which i never have) a problem but they are just truly unreliable...I phoned the call center multiple times reporting different issues when it's not even 3 months of having the contract. Firstly I was never informed that only after 3 months would I be able to convert to top as the sales agent was most probably just hungry for the sale was never informed of this and when I enquired yeah you know the drill there's nothing they can do until 3 months is over. ..then I reported not having signal mist of the time as it just disappears try to make a call no network, try to chat no network, try access jy schoolwork online no network... they apparently sent setting to my phone which I installed but yet I am still facing the same problem but then in this time of trying to connect with their weak or almost ni signal the data disappears. Then it comes to the fact that I had to get 10gig data every month for the first 3 months and when enquiring about it I had go wait 72 hours for feedback but still had to phone back as none made contact and eventually after that call the 1st months data got allocated.then they go and attempt to deduct from my account in the 24th of the month when I made it crystal clear that my deduction date is and will always be only on the 25th but no telkom deducts leaving me with a deduction attempt fee on my account as well as a bill that is sky high... and when I enquired yet again I had to wait 72 hours for a reply which u never got until I phoned in and was informed that the issue as been resolved but clearly it has not been cause I deduction of almost x2 of my installment went off and I had to phone in yet again where on that day i was informed that tgdg sang see anything on their side as yet and I should now waste my money on printing and emailing them a statement so they could sort out their ****... I phoned back again the next day and a dispute was logged and s refund request issued and yet again I will have to wait 72hrs for feedback to get my own money back which they took from my account, not thinking I also have other Bill's to pay or things to do with my cash.. telkom has been nothing but useless as there is no benefit in being with them as I've only had problems non stop. I never have signal that deduct wrongfully and I can topup. I am fed up sick and tired of this nonsense and clearly they are not doing anything to improve any of their services as long as they have free reign over your account and money nothing bothers them much.
