Uploaded dropped from 100mbit to 30mbit , QAM goes from 64 to 32 all time

Hey guys 
For last few days my 1gbit/100mbit line the upload has dropped to 30mbit , i need fast upload for work.

I noticed also the QAM goes from 64 to 32 all time on the upload channels in the router stats 

I go on status page and it says the following after doing test : 

Intermittent signal in your area

We’re looking into it. Check back here after 23 hours, and if there’s still an issue we’ll help you book an engineer.

Next time I do it it says all seems fine.     Is Virgin actually looking into this or not ?  If not, how can I speak to someone about this?  It seems impossible to actually report anything to Virgin via help pages,  what happend to the good old open a ticket via email and get a reply in 24 hours ? :D I dont wanna go through pages and pages of help and automatied AI rubbish 

Thanks for any help
