Disgusting Technical Faults Response

This has been a torrid time for our business, which we rely on internet for all our work. On the 20th of June I reported issues that our fibre internet is down and we need that fixed and i called the call center and logged a fault, got an sms saying they will attend to the fault within 3 days and they did not attend to anything, I kept calling like 5 times a day till to day the 2nd of July nothing has been fixed no techinician has come to attend our issue. On Friday the 29th I was told to take my router to Telkom Direct store and I did and got helped in the store and could connect to the wifi, but when i got back at work to reconnect nothing works again and all the employees are now working from home and at their expense on data which is bad for our business too. I really need to have the internet fixed urgently. This the worst company ever to respond to faults . I have a reference number till now noone is helping thats 12 days of waiting for nothing
