Try calling it in as a fault (on 150 VM line - or 0345 454 1111 others) and see what they say when they test your connection - the UK call centre is still picking up and calling at 08.00 gives the best chance of getting through quickly, although I got through recently in 20' at ~1pm midweek.
You can also text them on 07533 051809 include account name/number and what the issue is – replies may take longer.
Or, a VM person should pick this thread up as soon as they see it and be able to help in a few days.

We may also ask you for a bit more information so we can understand your specific issue like have you checked your speed using our Speed test site here. We also like customers to use a BMQ graph to gain more of an insight into your HUB's performance. We also may need to you reboot your HUB so that the data on the HUB's logs can reset, this helps the performance and also helps us identify any issues on our side.
