Lies to by game managers and game

I was at game pavilion trying to purchase a smeg blender on a sale clearance advert they had for all Dion items. The advert clearly indicates the items are for sale while stocks last. I had purchased the same blender before as a Christmas gift and manager Stanley Cele had confirmed that they know of the add as its all Dion stock. Today manager Sharithna Bajnath refused to give me the item. She **** and stated its new stock, when i asked to see the receiving stock invoice she refused. She then said she was calling her manager and fed him a lie as well of receiving stock. I asked to speak to the manager and she refused and hung up the phone. I have an advert which clearly indicates games promise but yet ge has managers who deprive customers of their rights. I call head office spoke to Roseline who indicated she could not help but would escalate the matter to her regional manager who she didn't know her name or details. Dissappointed at the store
