The worst customer treatment I've ever had in my whole life is in Kotton. On 1/9/2020 at 9:30 pm we…read morewent to Taksim branch to change 4 pieces we purchased on 28/12/2019 between 11:00pm-12:00. We had the receipt with us and we didn't touch the receipt since the day we purchased the items it was in the same plastic bag. A staff member called Helal told us to wait for half an hour so we did and then the manager I don't know his name told us to come back at 1:00 am or to come on the next day. We told him that we can't come back on the next day because our flight is on the next day in the morning and we'll be back at 12:00 because 1:00 is too late for us and changing the items shouldn't take 4 hours! We came back at 12:00 and they started Procrastinating and kept us waiting until 1:00 am. At that time we got angry. Imagine waiting from 9:30 pm until 1:00am just to change 4 pieces we didn't even want the cash back! They yelled at us from the beginning and threw the pieces at our face and left us to finish their job at the cashier. They called us "geri zekâlı" which means idiots in turkey. Thanks God I know Turkish so we left the items with the receipt in the shop and we left the place with the pieces we wanted to exchange our items with. At that time the door alarm worked and they told us they will call the police. We went to the police man in Taksim and then the civilian police came. We explained the problem to them and the rude manager who called us idiots told us explicitly to shut up both in English and in Turkish and laughed at us all in front of the police. They told the police that it is our fault that the barcode in the receipt isn't working"the receipt that we didn't move form the plastic bag they gave us" and that the cashier is now closed at 1:00 am! At that time we discovered that it was an evil trick from them since the beginning and that they didn't want to exchange the items since the beginning because the rude manager told us to come back at 1:00 am since 9:30 pm knowing that the cashier will be closed at that time. They insisted that we must come back on the next day and it's our fault not theirs. Our flight was already on the next day and they know that. We asked them for a guarantee that they'll return the items on the next day and they said that there's no guarantee and they don't guarantee that we won't wait for 4 hours again tomorrow. After five hours of stressful tiring moment at 1:45 am they exchanged the items after the police man told them to do so. Couldn't have they exchanged it at 9:30 immediately and save us the time and trouble? Couldn't have they treat us with respect at least? Neither the value nor the quality of the items sold in Koton are worth it as long as the customer service is that bad. We wasted 5 hours of our last few hours in Istanbul waiting for nothing. We had to call the police at the end to return the items. We could have spent that time on the Bosphorus or anywhere else in Istanbul. Helal, Isa"the manager who tried to hit us knowing that we're hijabis" and the manager who called us idiots. They all ruined a big reputation Koton made through out so many years in 1 minute. It takes years to build a good reputation and 1 minute to destroy all of that. They are ambassadors not only for Koton but for the entire Turkish citizens and they gave us a bad impression of all of the Turkish population. Added to that I am still wondering how can a big brand with a big branch in an area full of tourists don't have any employee who can speak in English or Arabic!!
