that if you pay extra for Saturday delivery

[maddening]

And the goods are faulty that they should arrange the pickup/ exchange on a Saturday if you require. Apparently this simply isn't possible grrrrrrr

Come on then. Name and shame!
YANBU!

Is it M&S? I've got ishoos with them in a similar vein

Argos, twice, the replacement was faulty too

Argos - they are awful! A friend of mine had to rearrange for something to be picked up for a return no less than three times and she was desperately waiting for the money to go back in her account. Eventually the money went back in and I'm pretty sure they never managed to pick it up!:s
