MWEB Fibre

Hi

I have been dealing with MWEB Fibre for a month now, regarding my home connection that is not stable. Everyday I phone MWEB and they kept saying they will call me back but they never call me back. This is the worst service I have received from an ISP that doesn't know what the issue is. My fibre from this month drop exactly between 13:00PM - 14:45PM. This has been ongoing for a month now. Why can't MWEB resolve this, why do I have to call them back to get an answer. I will not pay my bill for a service that doesn't work. If someone from MWEB see this post, please assist me. I can't work like this anymore
