Very Disappointed with Supersonic 5G Home Internet

I have been using Supersonic’s 5G Home Internet (uncapped LTE) since September 2025 at R549 per month. In January 2026, I received an email informing me that my subscription would increase by 35%. That is a massive and unreasonable increase, especially without proper explanation or customer engagement.

I made numerous calls to try and understand the justification for such a steep price hike, but I never received a clear or sensible explanation. Instead of resolving my concerns, the experience left me frustrated.

Because of this, I decided to cancel my month-to-month contract. To my surprise, I was then told that I needed to pay R600 for cancelling within six months. This makes no sense on a month-to-month agreement and feels completely unfair.

On top of that, the customer service experience has been extremely disappointing. Some agents were unfriendly, at times rude, and unwilling to listen properly. I have also been waiting to receive a callback to address my query, and no one has followed up to date.

Overall, I am very disappointed in how this situation has been handled. A 35% increase, poor communication, questionable cancellation fees, and unsatisfactory customer service have made this a very negative experience.

I would not recommend Supersonic based on my experience.
