Service was disgusting! Rude

My husband and i went to the cellphone section and ask about a blackberry that was on display.<br> The guy said there was no stock and that they discontinued the model. So my husband asked if they sell the display phone and very rudely he rep**** no he doesn't make the rules. So we nicely said to him but you don't have to be rude and maybe you should take it off the shelf so people don't think its for sale. So we walked away and he started repeating everything in his language to the co-workers in a rude way throwing his hands up! I don't think its very professional and the attitude we received was disgusting. Its a pity they don't appreciate there job!! When i looked for a manager he/she was now where to be found!
