Actually, Sunny, I had a very recent negative experience.
I returned a bottle of 2003 Balgownie Estate Shirez because it had a fault in there. The bottle was no longer active in their system.
I managed to find it on lcbosearch.com, and used the product ID for them to search in the vintages system. Lo and behold, the found the bottle, but the name spelt "Bagownie" - that's right, it was missing an "L".
Did I ever look like a criminal? I had the staff and the supervisor on duty telling me that it was "definitely" a different wine even though I proved to them that there's no "Bagownie Estate", and the picture on the BaLgownie website looks identical to the one I brought to them. Of course, they disregard the record that was correct on lcbosearch.com.
They insisted there's nothing they could do, because the spelling was incorrect. They sent me to a different store with a product consultant that could make the connection.
