Worst customer service

Supersonic must be the worst ISP I have ever dealt with. I have been waiting nearly a month for a new installation to be activated. Every single day I receive promises of call-backs and assurances that the issue will be resolved — yet nothing ever happens.

No one calls back, Managers simply log tickets but no action follows. The same excuses and back-and-forth continue endlessly with no progress.

To make matters worse, Supersonic invoiced me for a pro-rata period and a new month and deducted the money from my account despite the fact that my line had not even been activated yet — something they were fully aware of.

I have spent hours on the phone at my own expense, speaking to agents who repeatedly tell me that tickets have been logged, but nothing is ever resolved.

I am completely at my wit’s end. Supersonic delivers shockingly poor service and virtually non-existent customer support. I would not recommend them to anyone.
