Supersonic deserves a 000 Rating

I had tried to cancel my Lte with supersonic in April and get fibre with them. They said they will simply upgrade... nobody contacted me to do so. After many calls I still did not receive fibre and was still being billed for Lte which I did not want anymore. Which I.had sent to them on email to the email address you get on their site. Supersonic kept taking money from my account until I reversed it because I refuse to pay for a service I do not want. I had also tried cancelling on their WhatsApp number which they say call their call centre. I had also done that. You get no where. My latest call to them, the agent said send a email to the cancellation depot... first time of hearing of this....and to send them my previous emails.... done.... still no reply from supersonic but they still emailing me invoices. They are pathetic, useless, and unprofessional. They will not get a cent from me, neither will they receive anymore communication from me and if they don't want to collect their Lte modem well then that's too bad. The amount of bad reviews and complaints against them shows that they are a company that deserves a 000 rating. Well done supersonic!
