Not getting what I'm paying for.

I'm a paying customer that wants to get the service that I'm paying for. Every night for the last 4 nights my wifi does not work. It's on and connected but no Internet. That's not what I'm paying for. I need reliable Internet for work that I do at night. This is not acceptable. I'm on a month to month contract paying R580 a month. If this continues I'm cancelling this seeing that I'm not on a fixed term.
