Recently added TNT sports but it's not showing

I got TNT sports added to my package (and SKY sports removed) on Tuesday (19/10) via an App chat. (In another thread I've tried for a LOOOng time to get my on-line/App access to change my package myself but with no luck).

I received confirmation by email and also with a new contract copy on pdf on Wednesday morning - with TNT sports listed.

When I look at the channel list, TNT sports is still greyed out and I get the option to upgrade if I select one of the TNT channels.

If I DO follow the upgrade/select option, I get a screen that indicates an error (TS2/1/10-0-100164/302/400. Unplugging my streaming 'puck' and reconnecting it has no effect. If I try accessing TNT sports through Virgin TV Go, it's not available and I get the same option to upgrade.

Somehow it doesn't seem to have actually made it onto my account as a selectable option.

Every option I take when going via chat on the App gets me nowhere near asking about this particular problem. Very frustrating!

Can anyone (at Virgin) help please?

Thanks in advance,

Nigel
