No feedback or resolution

My Fiber connect went down on Tuesday morning (15 June), I called in to the call center and was told they would investigate, it's now more then a week later and my Fiber is still down. Only one has someone gotten back to me but that was only to tell me it's been escalated. Several time I'm told someone will contact me to provide an update but then no one gets back to me. I'm working from home and is extremely dependent on my internet to do my work, this is causing issues with my job and costing me extra money that I cannot afford. Almost every time I call into the call center it seems that there was noting done on the matter and no progress has been made.
