As has been said before,they offer you a price you don't like,move on and don't go to Trustpilot just for that. To answer your question,yes I've had a similar experience with PMT and I simply took my bass back into the car and drove home. They don't really want to deal with 2nd items in my experience based on the lowballing I've witnessed personally. They currently have a used Squier Vintage Modified Jazz Bass V on their website advertised as a Classic Vibe 70s and I'd expect them to know the difference based on their size and history. Also they're selling a used Gibson EB5 bass for £1,800 which has confused me seeing as they were sub £1k basses when new and not massively sought after even then.
