Telkom Service Non Existent - Trapped in a Contract with no Service!

On the weekend (end 30 and 31 May 2020), when calling out I received a message saying that I had less than R5 available. I am on contract and have never had a message like this before, however, I thought maybe as it's the end of the month I went over but it would be June soon. Come 1st of June and ever since, I cannot call out as my balance is now insufficient. Even though I have a contract and the money has come off of my account on the 31st May 2020. My data services work but I cannot call out at all? As for getting in touch with Telkom, it's impossible. Their call centre do not answer. I have phoned early in the morning, later in the day, at the present moment I have been holding for 15 minutes and 58 seconds. This is one of many calls like this. No progress at all. The chat line doesn't work either - even if I log in at 8am when they "open" - no one responds. I have emailed - no one responds. This is ridiculous - how does one get service from Telkom? There are so many complaints but all Telkom do is advertise what great deals they have to unsuspecting potential "victims" of their trap. Now I am trapped in a contract with no service. ICASA here we come. I'm sure there are plenty complaints already judging from those I have seen just in the last 2 days. Disgusting!
