Eating my money and still cut all my services

So Telkom is at it again! Telkom, you guy's are pathetic. In December 2019 I had called the contact center and had advised them that i would no longer be using my bank account that in which they were debuting me for both my mobile contract and my LTE contract. The agent advised that it would not be a problem and that I could go ahead and follow the cash payment every month provided that it is within the payment dates. I had been doing so since end of December 2020. No problems. Wifi always worked. This morning I get up and there is no wifi. So I wait til I get home from work to call the contact center to find out why is there a red light on my router. Only to be told that I am in arrears on my account of R409 due to unpaid debits. So which means, Your employee in which I had spoken to in December, took my call, listened cos she was paid to do it and did not change THE PAYMENT PLAN from DEBIT TO CASH on your system. Which is totally disgusting. Now your new agent Say's to me that I need to pay R409 I order to get my wifi back. And just for the record my mobile contract has also been out of use for 2 months now where I called the contact centre they say I should get a new sim card and that they will do a sim swap telephonically, I go get a sim card, call them up and they say to me they cannot do it! But the rude, impatient agent that I had spoken to with today, tells me that they have been doing sim swoops for the entire lock down and have stopped today due to stores opening today and that I must go to the store and they must help now cos the call centre can't! I still paid. Every month my cellphone contract was not in use, I still paid. I have have every God damn proof of my cash payments. I will not pay that R409 due to you people's uneducated staff members. I am starting to work from home next week. How the hell do I do that when you people cut off my wifi. Telkom, you people owe me big time. If you don't see how wrong you are in this message then you people are totally insane and heartless. I want a call tomorrow telling me about the way forward Contact Number: *** Mrs Reddy ***
