While the service by the personnel on site was very good, I find it totally unacceptable that is appears to be impossible to reach anybody at your company by phone. I had to change my flight and could not find a way to discuss my options with anybody. Instead, I was referred to website and chatbots that did not provide the answer to the specific problem I had. This created a lot of stress and uncertainty, and I was extremely disappointed that your company chose not to make a phone number avaiable Surely it must be possible for your company to employ somebody to answer queries by customers.
