No feedback, still no internet

Our internet stopped working last week on Saturday. We reported it via the app and received an automated response. Tried to call and could not get through! Eventually got hold of someone and they got SADV to contact me. Finally they sent someone out on Thursday, who was supposed to come on Wednesday, but they spent the whole day doing something and is still not working. I've received no feedback and all have no Internet. In this time of lockdown when we are supposed to work from home, I've incurred massive data costs using my cellphone to connect so that I can work. This is absolutely ridiculous service! The lack of feedback is causing so much frustration!
