Anybody else considering closing everything to do with Barclays after they've got their 125k Avios? Had nothing but trouble, Barclaycard and Premier account not linking, finally getting it sorted in branch but the £5 Dual Reward not being backdated plus all the 3D secure problems using the card online. I'd be amazed if I get the 100k Avios after 4 months without having to call them.
