Dukascopy Bank cannot log in

I could not log in to Dukascopy Bank for more than 20 hours. On New Year’s Eve on February 11, 2021, around 19:30, I could not log in either on mobile app or desktop. The customer service manager said it was because of the holiday. The floating loss was getting bigger and bigger. The customer service got off work early because of the holiday and left a phone number before leaving. But the call was in English. Finally, there was a customer service in Chinese, but the problem was not solved until the afternoon of next day when they closed positions manually after they went to work. I could not log in until about six in the afternoon. The long-distance call charges cost more than one hundred.
