Extremely low speed on superfast plan

[Kenindnic]

Hello,
Can we please get some help. We are currently on the superfast 100 plan however our speed is abysmal. 2.4Mbps!!!
We have gone through all the steps outlined in other posts on the forum to try to fix this issue but nothing is improving it.
Using the tpg supplied netcommwireless modem. FTTP connection.
Our results when standing directly next to the modem. http://tpg.speedtestcustom.com/result/c2bbabe0-747b-11ea-a5fc-8de489125bf7
This has been going on now for a month or two and it's getting extremely frustrating.
