I've done the same but for (CS), my little lad has a full cast on and broken leg so I've been trying for 3 days to get tickets in an area where there aren't as many steps for him.
Cut off about 20 times, passed to different departments and nobody seemed to know what they were doing or help in anyway and got sent back through the phones to where I began.
Finally got tickets this afternoon. His Mum and Step Dad are on membership cards and are coming too (its his birthday) can they get tickets next to us? nope! They have to wait until the window opens for them tomorrow even though we have failed to sell much of the allocation by all accounts.
I've no login details for my lad after requesting them, and I've no idea what points he is on as can no longer see.
Absolute sham.
