Disgruntled disgusted and expect management to address this before I take legal action for being refused my customer right

If I could give them 0 stars I would I requested to speak to a manager the agent was very rude and insulting I want to report the bad customer service I had, I tried making a payment via top up, they didn’t even inform me or have the decency to tell me it’s down or they’re having issues. I’d like a manager to call me because now I’m late for work because of them, I am really fed up of the service and I expect them to fix this within the next hour If I do not get this fixed I will be reporting this company to news24, enca, the voice and as well as the ombudsman, this is really bad service your agents refusal to let me speak to manger is really disappointing and pathetic if a customer requests to speak to manager there should not be any pushback at all.
