Supersonic poor service

Supersonic service is really poor. I have been without internet for more than 5 days (can you imagine working from home, i had to buy data every day just so i could log on and have meetings). I logged a ticket and keep calling on a daily basis, all they say is they are investigating. No one calls back, and when calling them i have to stay on the line holding for someone to answer the call, for more than 30min. This is really pathetic service. I thinking of cancelling their service.
