Constant "no number calls" since moving to IP Telephone from landline (Home) (Resolved)

So I received the deadlock letter today. Or rather a letter telling me I can now complain via https://www.cedr.com/consumer/cisas/

In order to complain they’ve asked for a lot of information so I’ve been forced to do a Subject Access Request https://www.virginmedia.com/help/dsar-faq

Means VM now have up to 30 days to pull all the call recordings, emails and webchats along with any notes their staff have left on my account. 

There is a chance VM could delay this and actually have 3 months to pull the info. 

Once I’ve got all the info from VM only then can I start my complaint with cedr and that can take 6 - 8 weeks for them to investigate the complaint. 

Of course all of this long winded process:

A: Is deliberately difficult to deter people from being bothered. 
B: Buys VM more time. 

I’ll persevere with it and I’m sure if others follow me VM will be forced to act eventually. 

At the moment VM’s attitude to the whole thing is appalling and that ultimately forms a part of my complaint. 

I can only encourage everyone else to go down the same path as the more of us that do, the more powerful our collective voices become.
