Caltex (The Orchards) worst service ever!!

I had the worst experience ever not once but 3 times. You can't ever buy milk there as its sour the 3 time that i bought there, when i returned the milk the cashier was so rude. Never in my life will i ever support Caltex The Orchards again i rather drive 5km further from home and support Sasol.

I have aksed the cashier also for the managers number or owner where he just refuses.
