Alcapone refuses to pay my refund

I bought a size 13 Palladium shoes for my son in Newtown than went home to KZN with the shoes which didn't fit my son. I phoned Alcapone a day later and spoke to Mohammed, he agreed that they would refund me my money if i was able to bring the shoes back latest by the 31st of December. I was able to courier the shoes to my brother in JHB on the 22nd and he went to Alcapone for a refund on the 23rd as they didn't have a fitting size for my boy. He didn't find Mohammed but another lady who was quite rude and completely refused to take the shoes for a refund saying they had dust on them. We had a screaming match as I tried to explain to her that my boy never even wore the shoes, they never fitted him. She also completely refused to give me her name. My brother was instructed to come see the store manager the next day and he arrived in time but that manager never showed and he was ignored thus brought the shoes back home to me. <br> <br> I feel this is day light robbery for them to refuse to take back shoes that never fitted and were never worn. I feel its my consumer right to be refunded as i spent money to courier the shoes in perfect condition back to Alcapone.
