Yesterday afternoon they suspended my telkom account

Yesterday afternoon they suspended my telkom account. I stay alone and I am currently self isolating as I tested positive for Covid 19. I can't go anywhere, so eventually my friend called me on the blocked number I can't make calls but I can receive calls. I asked my friend to make a payment as they say I have reached my credit limit of which I did not know about. As far as I know my wifi is uncapped. My friend made the payment but I am still blocked. The call center agent Matshidiso told me it will take 24 to 48 hours. I told her I am self isolating should there be an emergency I can't call anyone to take me to hospital. I don't have an alternative number. I asked to speak to someone higher she told me the person will tell me the same thing. But I have proof of payment. And I asked should I run out of breath and die what happens? Because sometimes just walking to the kitchen I have to sit down and catch my breath. This is a life and death situation and they are telling me I have to wait 48hours
