Am I Liable For Cost Of Return?

[Barsel]

I bought some fake colour changing candles from eBay.
They were describe as;
''Item Description:
Premium set of a flameless, colour-changing LED pillar candles made from real, ivory coloured wax for an authentic, realistic design.''
When they arrived I was shocked to see they were white plastic and really tacky. There were no screws for the battery cover and just not what I was expecting.
I started a returns procedure and they emailed me to ask if I would accept 20% off, I said no.
They have now offered me 30% off and have said this;
''If you still want to return , we will accept that. Please kindly note that for buyer do not want the item or order the wrong size and buyer need to cover the return shipping fee. Hope you could understand.''
Am I liable to pay the shipping fee when they have sent something that is not as described and contained no screws?

If the postage is deducted from the refund, a dispute can be raised and eBay will get involved.

If the item is not as described, there will be no problem getting the postage back from eBay.

Thanks again Corby, you've been very helpful.
