Makro Service sucks

In general I am a very easy going person and believe everybody has a job to do.I have been a Makro customer from the beginning of time,but after yesterdays experience at Makro Newmarket I will never put my foot in another Makro store.I went to the customer service to find out how to purchase a Gift Card and was assisted by a young lady that had the phone clued to her ear,she pointed me in the direction of the various cashiers,cashier of my choice was +- 3m from her behind the same desk.This cashier then refused to help me and pointed me to the otherside of the store to another set of cashiers as she didnt feel like getting her supervisor to authorise the card ect ect,my questions are the following 1) is it because I am white that she refused to help me 2)why be the cashier indicated by the "customer service" if you dont intend to do your job? 3)after insisiting on seeing a manager that didnt happen,she walk off(casual stroll) with out saying a word and returned with a supervisor and the giftcards without an issue so why should I cause a stink first before getting a service that you would expect ...again is it because I am white??4)when asking the supervisor what action will be taken "we will talk to her" during all this not a single response from the cashier as she just stood by with a casual grin on her face. and still no sign of a manager!! I am only one person in the greater scheme of things Makro wont care but believe me I will go without before ever putting my foot back in a Makro store again .
