Poor customer service

I am writing to express my frustration with the poor service I have received from Supersonic Fibre. I recently contacted them via their social media platform requesting assistance with changing my password. I clearly provided the exact password I wanted. However, instead of following my instructions, their team changed it to something else without my consent. As a result, I am now completely unable to access my internet connection. This is extremely inconvenient and unacceptable. What is even more concerning is that I have not received any response or assistance since reporting this issue. Being left without connectivity and without feedback reflects very poorly on their customer service.
