Ive not long joined vm and have been trying to get this sorted for a couple of weeks.
After some investigation and reading this forum it appears that the parental controls on vm do not work at all. All websites are accessible even with controls switched on. With Sky you had to specifically allow harmful sites like pornography/violence etc and access was automatically blocked. With vm they are allowed by default and the blocking has no effect.
The blocked site list doesnt work and it appears it has never worked. Internet pausing of specific devices doesnt work and seemingly has never worked.
Customer services will take you through a pointless process of re setting the hub with full knowledge it wont work.
The only option is to switch providers. Im pretty sure we can cancel our contracts without penalty as vm are not providing the agreed to services.
