Am trying to buy tickets in the resale process. Every time I select tickets showing as available I get told they're not available when I try to checkout. I've tried all different prices/events/no. of tickets.
So, I can accept that someone else might beat me to it by a simultaneous purchase but why then are the same tickets still showing as being available over an hour later and yet when I even select 1 ticket I still can't buy them because they come back as unavailable 
I know I'm not alone having seen people complaining of the same thing on the Telegraph site.
So, my Q is, has anyone been successful? And, more importantly for me, does anyone know whether more tickets for resale can be added during this resale window up to 6 Feb or are all those tickets that people want to sell already on the site and it's just that people have till 6 Feb to buy?
