Where has the manager gone.....is he a real person

Wanted to buy a number of pole garden lights. Asked in person for a price and was offered 6.perc discount. Asked for a written quote. No.discount offered. Gent said no stock will.order and then give discount. Received email yesterday. Price increased now on sale at same price as normal price and no discount. Asked to speak to manager. Tried phoning manager. Really bad business practice . Won't see my.R10k spend.
