@Manesh_parmar I see from your previous posts on here you have had issues with Web Safe not working in the past. I'll ask the @ModTeam to get one of the forum team to pop by and try to assist as it seems there is something not right with your account for this to keep happening.
Personally I would recommend you look for a better parental controls solution because, as you have discovered, the VM offering is not reliable. It is also very easy for anyone in your household to bypass the controls by setting a different DNS on their device, as the filtering only works through the VM DNS.
Open DNS provide a similar free (but arguably better) service to VM with DNS based parental controls:
Open DNS like Web Safe can be bypassed at the device level. If you need control at that level then look at the device's parental control settings.
If you want central control on one device then I'd suggest a third party router and put the VM hub into modem mode. Some suggestions here of ones with good parental controls:
My setup: VM TV 360 box, M350 Fibre broadband with Hub 3 in modem mode connected to a Netgear R7000 router. Telewest/VM user since 2001.
