False advertising with inferior products

Purchased a ring online with a very clear description that mentioned 9ct gold metal in both the heading and the description, including a moissanite.

The ring that arrived was 925 stamped silver, without a certificate of authenticity for the stone.

When queried with the Bash customer services centre, I was told that there was nothing that could be done as the item did not exist. It does exist, and is in another listing with exactly the same description but at a different price.

The solution was to offer me a 25% off voucher and a refund - but I want the ring that I ordered and that was advertised. Dealing with customer services is a nightmare - backwards and forwards with no resolution.

Nil out of 10.
