"Activating" a Contract information sheet

I won't go into the full story as it's long, but in a nutshell VM contacted me two weeks ago because my deal was up.  I was at work and couldn't speak for long, so I asked for call back and an email quote to upgrade and have Mega TV included.  I was sent an email with a Contract information sheet number, but this hasn't been activated as I missed the initial rep phoning back because I was still at work.

I've had numerous reps phoning since then, trying to offer me a new deal.  When I try and point them back to the previous quote, they are evasive - making excuses that they can't access the details.  It's almost as if they don't want another rep to take the commission.

Phoned 150 yesterday and spoke to a lady who said leave it 14 days and phone back if it hasn't kicked in.  I have zero confidence she's activated the original quote, I had to read back all the details on the Contract information sheet, even though it should be on her screen!  She was lovely but seemed clueless.  I don't want to wait 14 days if she's messed up, I'll be paying a larger bill.

Are there any forum Mods viewing who can take the quote number, see if it's in progress and, if not, get this implemented?  Many thanks :)
