lost package without noticing customer

Foschini had an online beauty sale on Smashbox so I ordered items at a discount. After 3 weeks of waiting and not receiving my order, I receive an email saying I returned the items and they are refunding me even less than what I paid on sale. When I logged a complaint and query about this, only then they advised me that they lost my packages and will give me a R100 voucher, trying to force me to purchase from them again after this absolutely non-existing service. If I didn’t contact them, nothing would have happened. So tired of poor service in SA and no consequences for brands who form part of this. Don’t offer online sales if you can’t deliver on paid services.
