Are you using a wired Ethernet connection to the VM hub or a wireless connection? Wireless is easily disrupted by a number of external factors, so a wired test using a device with a gigabit Ethernet card is the best way to get a true picture of what speed your line is able to achieve. It also helps to pinpoint if the issue is with the wireless or your line.
If you go to http://192.168.0.1/ (or http://192.168.100.1/ if you are in modem mode) to get the VM hub GUI. Don't login (unless you have a Hub 3 and this is your first visit to the hub GUI, which does require you to login) but instead click on Router Status which is either a button in the top right of the screen or a text link at the bottom of the screen depending on which hub you have. Click on the Downstream, Upstream and Network Log sections and copy & paste the figures from those screens and post them here, don't worry about the formatting or you can post screenshots if that is easier. Be careful to edit out or obscure any reference to your WAN IP or MAC address in the log to protect your privacy.
The community can have a look for you and see if anything in the figures looks wrong and advise accordingly. Or you can wait for the VM staff to pick up this thread (can take 7-10 days) and run checks on your line.

Sorry to hear that you're experiencing slow speeds, I know this is frustrating.
Checking your connection I can see that we're currently working on a fault in your area under ref: F002977692 which is due for review on the 8th March. This fault is known for reducing speeds especially peak time hours (evening and weekends). While this is on-going we would recommend using an Ethernet cable where possible.
Sincere apologies for that, let me know if you have any other questions.
