No internet for a Postnet in Queenstown

We have just changed our business ISP to Telkom we did this on the 18 December 2019, to this day we have not had internet. We run a Postnet in Queenstown and one can only imagine the effect this has had on our business. We have been calling the call centers everyday this year being sent from pillar to post. Till today we have no internet. When we ask for a technician, none is sent to us as we are told it’s not a technical problem. We have tried everything and no one is helping us. We need a technician ASAP. Please can someone from Telkom help us. Our business is threatened to being closed by Telkom. And I will sue if Telkom if that happens.
