Trendyol Order Delivery Victimization

I bought 3 products from the Trendyol app, one of which was cat food. I chose a pick-up point as the delivery address for my order to be delivered even if I was not at home. However, they did not deliver my order because the pick-up point was closed. Three days later, they called me and said that they sent me an address update link, but when I checked my messages, I saw that no such link was sent. Although I talked to Trendyol Ekspres on the phone several times every day between January 9th and January 12th, they claimed that I did not do such a thing and did not update, even though I explained the situation and gave my address. Using the links they sent, they canceled and returned my two products without asking me and without my approval. My cat is currently not eating the food I temporarily bought for her from the market, I am a victim. I will not order again, it will take a long time for the order to arrive and there is a minimum of 200 ₺ difference between the price at that time and the current price. I asked to talk to an authorized officer to complain and explain my situation. They said they noted my call and said I would be called within 24 hours, but they didn't do that either. Trendyol made me very tired both financially and morally. They are spoilt as they grow day by day. I will not shop again and I will file an appeal to the Consumer Rights Arbitration Committee.
