Business LTE - unusable between 6pm to 10pm every day

I have 2 business LTE from Vodacom. Both these are lately unusable, now for the past month plus, between 6pm to 10pm, sometimes I can only use internet at 11pm. I do not stream or download movie content, just use it for work. On average, dusting this time it takes 3 min just to open a google search page. This hello peter page took 2 min.

How can we sort Vodacom out, why is it allowed for Companies to do this, users pay, but they cant use the service and the company, in this case Vodacom just get away?

How can we sort this out for once and for all - these companies should be fined properly - does the consumer act assist in this case.

So, Vodacom will probably come back with some lame excuse - how do we address this?
