Coles Supermarkets Australia

I am a regular customer at miami one coles, I arrived today at your store 6am to purchase my toilet paper, I went to the cash desk which had only two lady's serving on each till, one was the thin middle aged woman with long dark hair in a pony tail which from past experience I new she wouldn't be nice, as she always has a bad attitude towards myself and wife, we often see her rolling her eyes at other cashiers when serving other customers too.
Anyway, I went to her (not through choice) and continued to pay for my pack of toilet rolls, while I was paying I asked her politely to confirm that I was only allowed 1 packet of toilet rolls, instead of a polite yes or no reply, she asked in a really sarcastic manner, "why how many do you need", I then told her I have a large family but she ignored me and began to shake her head, I got a bit pissed off at this point because of this attitude she always portrays and said to her " why are you shaking you head, she just mumbled nevermind and never even gave me my reciept, just put it ontop of my toilet rolls, this got me mad, so I took my rolls back to the car and went back in to purposely piss her off, and picked up another pack and purchased them (seen as I never got a straight yes or no to my question about how many I was allowed), she done the same thing again, no greeting first or second time, snapped my reciept ontop of the rolls again with no eye contact what so ever, so I done the same thing for a third time, this time she had the store manager ready for me, he was almost like he had just stopped some big robbery, not introducing himself to me just came up and said you can't have them mate, so unprofessional and threatening in his tone and stature, quite frankly looked like he needed some lessons in dressing himself, now bearing in mind I spend over $250 per week in this store and have since it opened, I expect a bit better service and explanations from the staff, most staff in this store are fine apart from the above.
So today my wife and I went shopping at another supermarket in stocklands not far from miami, the staff were polite and way more helpful, I hadn't noticed this before due to being loyal to coles, but now I am seriously thinking about using the woolworths at stocklands where I am made feel welcome, if something is not done about this rude woman and manager, look forward to a reply
Thank you for your time
