Vodacom signal reception

I run a small business and I heavily depend on internet access. Vodacom in our area is lately more off than on - like yesterday it was off the whole afternoon. They blame it on stage 6 load shedding, but yesterday we had stage 3 and stage 4. Surely that is not my problem! I pay full subscription every month and I am not getting what I pay for!! Income from my business has dropped substantially and all I can do is hope that Vodacom eventually attend to the problem! The least they can do is reach out and don't charge for times we have no service!
