Sold a *** in a bag

It's 7days having a wifi that doesn't connect devices and radious as advertised

I called customer care they put me through tech support who open tickets and closed without resolving the issue, then told I need to call Accelerit as network provider and still no joy as Accelerit send me back to zoom and each day I call without anyone bothered to see my issue through..they all pass the buck to next person or next team

I am paying for a *** that was sold in a bag and now I am stucked with it Thanks to Zoom fibre.
