I'm also not quite sure what to make of this. I haven't bought an awful lot from Carpkit, but when I did Simon provided an excelent service. So has every other vendor I have bought from in the US, including Resistance Tackle in the past, Wackerbaits and Big Carp Tackle. All very profesional with an outstanding service. Never had an issue.
We don't know if the initiator of this post has had personal beef with the vendor, or something else entirely initiated the online dialogue. Or maybe Simon really messed up. Who knows.
But either way, I am not a big fan of trying to burn a business online. It looks bad, it feels bad, it smells bad. There are better ways to handle this.
