Mango Taking the Products But Not Refunding the Money

I realized that I have not received refunds for many items I returned from my purchases made through Mango's official app. In the app, some items still show as shipped, while others do not even have that status. Despite a long time passing, there is no information in the app confirming that these products have been returned, nor have I received any refunds in my bank accounts. Since I know they send an email when a return is processed, I checked my email, but there is no information about any returns for these orders. Until yesterday, the My Purchases section of the app would not even open, showing an error each time I tried to access it. It finally opened yesterday, and that is when I noticed the issue. For example, in the order with number ED808I, I initially ordered two pairs of pants and later ordered the same pants again in the order ED9KKD. I sent both pairs of pants from the ED808I order for a return, but it appears as if I never returned them. Similarly, in the ED9KKD order, I sent two pairs of pants for return, and as shown in the image, Mango arbitrarily accepted the return of one pair and rejected the other. Additionally, I returned a skirt from the EC6IDW order, which still shows as shipped, but no return has been processed for over a month. Reviewing older orders, I found the same issue with an order from a year ago—order number DXN3F7 is still marked as shipped and has not changed to returned. As a result, I have neither the products nor the refunds. How can you keep the money and hold onto the products? What kind of professional ethics is this? You have no reason to reject the return, and even if you do not accept it, why have you not sent the products back all this time? This is completely unacceptable and lacks any explanation. I have made many purchases from Inditex over the years, and I have never experienced such a scandal. I am a doctor, my fiancée is a lawyer, and I demand an immediate and full refund, or I will initiate legal proceedings.
