Horrible customer service and no connection

I joined this Fibre company in 2022. I didn't notice anything off as I just used the internet for 3 mobile phones at that time, (I took the entry level package 20mbps - 10mbps). I started working from home last year and I had connection issues, everytime I tried to contact this company they gave automated responses that "someone will be in contact with me" but that never happened, I spoke to the guy that signed me up, he would reply days later and say that he will send a ticket. After that still no updates. Eventually towards the end of 2023 I was told that "the reason for my connection issue is that my package is to low to work from home"( remember I said I only use 3 mobiles) but that's fine I didn't want to argue and this was my job on the line so I asked which package I should get and the lady told me the middle package will be more than sufficient for my home since there are only 3 people using the internet. I upgraded my package and still had the same issues , however I went on maternity leave 2 months later so I didn't get to really see if there was a change. I went back to work in July this year and I sent a message to fly.cool, 2 months later (September) they send a tech to my home, he finds out that the wires in the box out of my property is burnt out. He told me that if i did a speed test it will show high speeds but my connection will always be slow. He added a new wire, i had the best connection for 5 days and it went south again. I messaged their whatsapp number and they send someone end of October, same issue again(wires burnt). Im not sure how this is happening but it seems like they are not interested in doing a proper job and just doing short cuts that is why this might be the reason for the horrible connection. It is now December, I sent 5 emails and still have no response on what to do. I wish I had more options to choose from. I WOULD NOT RECOMMEND THIS COMPANY TO ANYONE.
