Long wait, flawed merchandise, poor ethics

Waited over a month to receive an order of 4 cushion covers, two of which were ink stained. Followed the complaints process: send images of the packaging, item codes and flawed goods. No response. Resubmitted and was asked to resend evidence. Was then given three options: use flawed merchandise, or return said merchandise at a cost to MYSELF to reship to China, or get 50% refund. Having paid for intact merchandise, and the postage already, reluctant now to share banking details with organisation for refund. Asked for replacement of only stained covers. NO response to date. Have deleted app.
