Disgusting customer service

If I could give negative stars I would. From day one the account department has never been able to correctly calculate amount owed. I have been overcharged and have been communicating with Renee Ramatlotlo who simply reads your email and closes the ticket without bothering to respond. From 3rd November to date my issue has not been resolved and I keep getting overcharged. Rene's manager, Sam (if he exists) also refuses to take my calls because he has always conveniently left the office when I request to speak to him. I'm just glad I signed up for 3 months on trial. The next 2 months will be difficult. Imagine spending more on airtime than the actual fibre services!
