Poor service

I went to truworths forest hill yesterday to buy Estee lauder, the was a lady assisting me with choosing colour. There was no prices on items, I asked the price she said 650 and when I got to the till was R685.i told the cashier that they told me its R650 which is what I can afford,I think it was the manager at the till, tall, light and wearing a ring,. She said whatever the sales assistant told me has nothing to do with her. Am so disappointed, month end am closing my account, I don't wanna see truworths anymore. No one had name badges on, I don't even know their names
