Zara Menlyn gave me the worst customer I've ever experienced.

I purchased men's shoes from your online store in December 2020. And unfortunately couldn't gift them to the person I had intended to give them to due to their ill health at the time. The shoes arrived on the 31st of December 2020 and were collected on the 12 of January 2021. Today I tried to exchange the shoes at Zara Menlyn due to the fact that they didn't fit my partner but I was told there was nothing they could for me as the 30 day period to receive a refund or exchange had lapsed. To begin with I never asked for any refunds but instead I just wanted to exchange the shoes. I was asked various questions as to why I had not returned them on time and I ended up having to divulge personal information regarding my partner's health situation at the time. I found this to be invasive and uncalled for as a custoner. But even after giving such information, I was still not assisted and I requested the store manager, who came to the counter and didn't even bother to explain your store's procedures but simply said that I should refer to what the teller had informed me and proceeded to give me your customerservice card and left it at that. I am kindly requesting a way in which to deal with this situation and further get an exchange for the shoes I had bought for my partner whom I so wished to gift at the time.
