I bought a bass of them recently - a good deal on a nice guitar but their sales skills are zero (this wasn't Mark but his assistant)
I was shelling out nearly £900.....I wanted to be 'stroked' (not physically but you get my meaning) and made to feel welcomed and a valued customer and instead felt like I'd just been to Aldi to buy a bag of peanuts.
Mark...if you're reading this, looks like you need to send your lads down to Wunjo for the day to see how it should be done. No need to be Arthur Daly / Delboy, just be nice to people and ask if customers want anything else (strings, straps, bags...whatever), which will generate extra sales for you!
