I made a mistake when ordering 3 mattresses and one was the wrong size. I was told by customer services to take it back and swap it, I explained it was unpacked. They reserved the bigger one for me. the manager then refused to take the wrong one back and said they were 'always' having trouble with customer services giving the wrong advice. Store manager called customer services to get 'authorisation' to take the item back to be told there was no record. Beware of using the 'chat' facility as it is deleted when you log off, use the phone as they record the conversation (and so can you). Even explaining that there was little chance of seeing the item was the wrong size without unpacking didn't cut any ice and it was up to the store manager to use their discretion. They said my mistake wasn't their problem and they had a business to run, I say show me a business that does not experience customer mistakes; it is how you deal with them that keeps people coming back. They appear to be trying to go up market with the new 'Collection', pity the customer service doesn't match up. Don't buy from Argos, they will make YOU pay if you make a mistake, even if the item is unused and resellable.
