Avoid Supersonic - Unfair Billing Practices and Lack of Customer Support

I had been a customer of Supersonic for 4 months, but my experience with them turned sour when I decided to cancel my services due to the sale of my property in November 2020. As per their cancellation policy, I notified Supersonic via email within the required notice period. I even received confirmation of the receipt of my cancellation on the same day.

Despite having my account fully paid up to December 2020 and returning their router as per the contract terms, I was shocked to receive a claw-back invoice from Supersonic in May 2021, five months after my cancellation. The invoice provided no context or explanation regarding the exorbitant amount they were charging me.

In response, I reached out to Supersonic via multiple email addresses provided, including ***, ***, and ***, as their phones were never answered. However, I received no response to any of my inquiries.

Moreover, the charges on the invoice far exceeded the cancellation fee specified in their policy. According to their own terms, I should have been charged a cancellation fee of R899 (inc VAT) if I canceled within 12 months of activation, but the amount they demanded was significantly higher and unjustified.

To add insult to injury, after years of silence, Supersonic suddenly resurfaced in 2024 with a letter of demand from their lawyers, threatening legal action for non-payment of the disputed amount. This behavior is not only unfair but also demonstrates a complete lack of regard for customer satisfaction and transparency.

My experience with Supersonic has been nothing short of a nightmare. Their unfair billing practices, lack of communication, and failure to provide a breakdown of charges make them a company to avoid at all costs.
