Worse than poor service again Sonic

My Wifi has been down for almost 12 hours. I contacted their so called whatsapp group to get assistance with very little help. This morning, I called them at 7 as per their operating hours but no one was picking up on their side. The first call only got answered after 8am. The technician who was working on my case promised to call me back at 9. Needless to say he did not.I've been sent from pillar to post trying to get hold of him for the past 2 hours including being put through to numbers that hung up even. I spoke to Marilyn at 923 who said I would get a call back. Well its 11 am and I had to call back as no one has gotten back to me. Only to be told now that the whole team is on team building. Worst part is this is not the first time I have recieved such poor service.I let them know this is urgent as I was waiting to resolve this before going to work this morning and I have academic assignments to work on this weekend.
