Worst service ever!

When I first started using Telkom and initially bought my first cellphone contract everything was fine however issues started when when I upgraded my contract, Telkom no longer debit on my account and I am being failed debit order fee which are plus R206. I called the call center with no available agent to take my call so I opted for chat, worst experience ever, the agent did not know her story. I asked her why wasn't I debited for the previous month and she responded, you were debited I then asked her when? because on my side it doesn't show that there was a debit done, she then texted, oh sorry you weren't debited and I asked why? She responded I can't tell! Explained to her this is the second month I am experiencing this and I get failed debit order fee each month including this month, she then responded by telling me that I will have to make a manual payment because because if I do not, they will charge me. I asked her how is it my fault Telkom did not debited and she responded 'unfortunately it is what it is' asked her to transfer me to her manage which explained she couldn't hence she's working from home however she will ask her manager to call me even today I am still awaiting for that call. Over the weekend I decided to go to Protea Glen Telkom store, explained to the lady my situation and asked her if we can contact the call center because I am not assisted on my own, she told they had no land-line and she also won't be able to help me, only the call center can assist regarding this matter! I am so disappointed and I want to cancel my contract as soon as I am able to pay it off!
