Poor customer service!!

What an absolute disappointment!! We went into the shop to purchase binoculars, while waiting in the que Sipho one of the guys who work in the shop shoved a more expensive brand into my hand and said that one is better, i told him the one i have is sufficient for what i want to use it for then he continued to tell me i shoulf remeber his face when im dissapointed in my purchase and I'm making a mistake buying the cheaper one, i asked him why the sell a bunch of different brands etc if that specific one is the best?? Then when we moved to the till to pay he continues to tell the guy behind us that it's a mistake and basically dissing us for purchasing a '' cheaper'' one. Why must i spend R2 500 on the same thing just a different brand and something i don't use daily just for the purpose of using it in the park... I did my research and the brand we took (Tasco) is well knoen and recommended by many the only function being it's not water proof...
