We had to wait over 6 weeks for our corner sofa to be delivered, when it did come they delivered two right hand pieces, instead of one right hand and one left hand that slots together.
Despite their extensive network, Argos told me they couldn't get the right part until 3 weeks after. Which tells me they didn't actually construct the sofa properly, or there would be the corresponding left hand sofa somewhere that they could deliver.
The were reluctant to give me any gesture of goodwill for the inconvenience. eventually they gave me a partial refund, but wouldn't even pick up the redundant part of the sofa until they delivered the new one. Which is even more of an inconvenience.
They also delivered some bedding, but again one of the pillowcases did not have a reversible side, it was the same on both sides, however the other one was made properly.
It just sloppy work, I have always bought from Argos however the manufacturing and delivery of these items has definitely made me think twice about using them again.
