Whoever laid the main fibre pipeline screwed up. The external installers said the piping is blocked (dirt or water etc) thus unable to blow the fibre cable through, which apparently is affecting several houses along my street. Have to wait for the subcontractor who did the job to unearth the main line and fix the problem. This will most likely take another month at least, since both the external and internal installers will have to be rebooked after the 10 day period for Ultrafastfibre to fix the piping.
I'm not sure if this is a common occurrence, or was it just bad luck/carelessness by the contractors. Definitely not happy about this since we are stuck without proper internet (been using mobile stick for over 2 months now).
