Terrible Connection & Customer Service

I have had connection issues with my fibre line for the past month. I have reported it previously, but it keeps happening. At least once a week for 2 hours at a time, the connection just drops suddenly. Today again - no connection and on 23/04 - no connection for 4 hours. I have logged a ticket with Supersonic on 23/04, a week later and no response. I sent a whatsapp on 23/04 - still waiting for reply. Today I called the customer care number again, was holding for 10 minutes and no one answered. Seems like the only way to get a response is to write a bad review on Hello Peter.
