I phone Argos this morning about my pre-order from 15-July as it said that I would be contacted about delivery by 18-Oct and I'd heard nothing. In addition their website was actually telling me it had been delivered.
Argos say that they we're 'delivered' to Royal Mail on 05-Nov, they apologise that it's going to be late and that the late delivery is their fault. I should receive it within the next 5 days!
I'm positive it said delivery ON 10-Nov on their website back when I ordered it. The whole point of pre-ordering was to make sure I got it on the day, especially when they were happy enough to take payment from me straight away!
