False advertising 🤬

Dischem is false advertising🤬 I ordered Brutt aftershave and paid online,the accept the order and status showed process 2 days later they called and tell my they out of stock I ask the lady so they are refunding me,and she said yes. When I call them today they told me they don't refund the amount back they put it as a credit for when I buy online again. So needles to say I don't buy online at Dischem what means I'm losing the money!
