Raleigh Bicycle Damage

I purchased 3 Raleigh bikes from Makro on 19/12/2020.

All 3 bikes have rusted chains, rusted nuts and rust in the pedals.

Two bikes have training wheels and both sets of training wheels have tread that's come off on one wheel.

Two bikes have pedals that have cracked.

I understand that with the massive amount of rain, rust and sun damage is to be expected, however for bikes that are just on 2 months old, this is ridiculous.

I paid R3000 for 3 bikes which are badly damaged in less than 2 months.

What options do I have under the warranty for repair or replacement? I still have the receipts for all 3 bikes.
