Herotel bad Internet

So I had banking issues where I had the correct banking account with incorrect bank, was waiting for my money to be paid back in my account so that I could pay my Herotel which I did then I paid in advance, I was informed that my account was un suspended , I logged a call and I was told there box on the wall was faulty and they needed to send out a technician which they did. When the box was replace leaving it hanging from the wall and paint taken off my wall, I received a a Bill of R850 which I did not agree to it. I email Herotel. No one in any of my conversations told us that this would be a chargeable call and that we had to pay for there equipment that is faulty. And I explained the situation with the device hanging from the wall and the paint that has been taken from the wall. That was all fine until we still cannot connect we still have no internet and we are being ignored by Herotel.
