Volt Benefits Not Yet Received.

We are on a 500mb package, it was installed just over 2 weeks ago. During purchase and installation we were told our O2 volt benefits will boost our speed to 1 gig. I was told to allow 14 days.

14 days have now elapsed and I am still on 500mb, my volt benefits are active on my O2 account, but any virgin media section returns errors. Could someone look into this for me and fix this?

Thanks
