Large items.

I have ordered a couple of new sofas from a company on eBay. The company has excellent feedback with 99.6% positive from over a thousand sales. They have now sent me tracking details for Evri, the tracking number works but all information I can see says Evri don't deliver large items such as furniture unless it is flat packed and weighs less than around 12kg which obviously sofas are not going to be. Do Evri have a separate sister company that handles these types of things or should I be worried?
