No internet every weekend

I would like to lay a complaint about the Vodacom Business wireless airfibre department. Ever since January this year I have been having issues with no internet for days . This is ridiculous if the Hub is a problem then why can't you fix it. Loadshedding is not going away so make arrangements for the hub to still work during Loadshedding. I am tired of the excuses. Every weekend it's the same story the internet goes off on Saturday and is only fixed on the Monday. Yet we are still billed for a full 30 days even though we only have internet for less than that. I want this fixed if you cannot provide a service let me know I will find other companies who can assist I will cancel this damn contract.
