Zara clothing

My daughter purchased a pair of denim shorts just before March and lock down. She had hardly worn them and they stared to fall apart. I contacted Zara during lock down and they said to bring them into the store once it was possible. My daughter had pneumonia and mother COVID so the first time we ventured to the mall was last week. I was told it was now to late to return them. The shorts cost over R350 and she wore them once or twice as they could see based on the fact they were brand new other than the pulling apart of the fabric. Due to COVID I would have expected a better returns policy
