Now TV broadband test is showing 75mbps download, every other speed test is showing less than 20mbps, it has been appalling for days, it is supposed to be guaranteed at 56mbps. it is about time you provided what I am paying for and what you guarantee.
This is a customer to customer forum so saying “you” as no bearing at all.
Is the connection through Wi-Fi or Ethernet?
Try splitting the Wi-Fi bands.

If that fails do a factory reset to the router by holding the reset button for 15 seconds.
Worst case call the broadband team in the morning using the number from the link below.

Us? We’re just customers, same as you, prepared to offer advice, but not to take the blame you ascribe to Now.
Now’s broadband test just shows the maximum Now can send over your line. But given how fast the WiFi drops off, you should do an independent speed test (I use fast.com) either over Ethernet cable, or with a WiFi device as close to the router as possible.
And if the speeds are below your guaranteed minimum, get in touch with Now Broadband support on 0330 041 2518 and get them to investigate the issue.
Unfortunately, the "guaranteed speeds" are sync speeds, if you aren't able to achieve those (less 5-10% for overheads) on a hard wired connection, that is another problem.
You need to report the problem to Now, and see if they can resolve it.
