Anyone has experience with Argos home delivery for large items?

We've ordered a fairly heavy sofabed to be delivered, we live on the second floor and there's no lift. Due to me being at work my bf will be by himself when it comes (not that I would be any help carrying it up the stairs); I rang Argos to make sure the delivery people would carry it into the flat and the lady on the phone said it could not be guaranteed for health and safety reasons (which I understand). She did make a note on the file to make sure the delivery guys would be aware of this.

I had the same answer from ao.com when we ordered our fridge but their delivery team carried it upstairs without a complaint.

What can I expect from the Argos delivery people?

And anyone has an idea what we can do if they refuse to carry it upstairs? We just moved to a new area so no friends/family around to help and we have not met the neighbours yet :(
