COJ Billing

I moved to pre-paid on 9 December 2022, I have been buying electricity tokens online, but COJ keeps billing me normally supply and all the network fees as well. Have made about 15 calls in 4 months, have taken off 4 days to go to their offices, still not resolve. I dealt with Thoriso Phala from COJ, have followed up by mail 3 times with him, no reply, went to their offices again, there he is again promising to call me today, again nothing. Worst service ever, avoid living in Johannesburg if you can, as it's falling apart.
