Hello.
I did have Phone, Fibre, and TV package. I cancelled the TV package a few months ago, and have noticed a reduction in connection speeds of around 10-15 Mbps on speed tests and around 1MB download speed (Typically a drop from 2.5/7MBps to 1.5/8MBps). I am not saying I think it's because I cancelled the TV aspect, but that is the only thing that has changed.
