bad communication from Cell C to their customer needs and queries

Currently, I know that I am in the wrong for not paying my account or contract with Cell C. But I did, however, send them an email almost a week ago and until today I haven't had any response whatsoever, no calls, nothing as I am trying to make an arrangement about my account. I get an SMS to call the customer care, but I only get a recording, what does that help if I cant call or reach out. And still my email was ignored, Cell C has a bad way to respond to emails! So where does this leave me? Even for my mistake for not paying on time, I really expected more from Cell C!!
