My last complaint to supersonic

Supersonic employee's are failing to apply permanent fix for the issues I am constantly facing.

My speed always drops to 2mbs because for some reason my account is always downgraded/moved to a guest account even though my account with supersonic is fully paid, it cannot be that I have to contact them every now and then, as i write this complaint my speed is lower than what I paid for and on my supersonic profile account it shows that my product is offline.

I also informed them that the power adapter of their router burned and i had to use my own adapter and that the router is not stable 'till this date no one has come to replace it.

This platform is my last resort to get them to appoint a tech who knows how to correct this permanently as I will never ever call them again regarding this my next call will be to terminate the service agreement.
