Poor Service from Bronberg Connect

We have Bronberg as service provider and since Lockdown had them out 3 x to fix our connection. Then they send a guy to replace equipment as they say it was "old" - this was replaced on 8th June and since then we have not had a connection. You call send messages, log calls and no ones comes back to you. Our kids were unable to attend class, hand in school work, we cannot work and yet we pay for a Business Connection - and still expected to pay them but not getting what we pay for. I am at breaking point with them and not sure what to do anymore. We do not have fibre as we live on a farm north of Lanseria.
