Clowns running a circus

Phone guy to ask for official quote for item being advertised on gumtree (6kw devel inverter for 9995.00) he then says I must wattsup him so I did then sends price for 14000. I asked why I the price difference so he says those are sold out yet add posted same day as my request then sends me picture of another for 11000 but on add it’s 8995 so I phone him and his reply was whites must pay more . Now I get nasty watts up messages saying we are thieves and fools. What a professional company.
