Cell C Fibre - very bad service as there is no one to talk to

I am trying to get hold of someone in the collections/finance department of Cell C Fibre - i have a ticket (CF085126) for Cell C Support but there is no support as they cannot help me with my issue. I need to speak to someone in the accounts department. My account is blocked and i need this for work. I am at the point now of moving to another fibre provider as it seems Cell C is not interested in keeping customers who have been with them since 2018.
