"I am appalled by the dishonesty, incompetence, and deception I have encountered with Iberia. I have spent the last 7 hours attempting to change my flight, which I purchased with the option to alter my return date. However, Iberia has made this process unnecessarily complicated. Online changes are unavailable, and their announced option to use WhatsApp for assistance is non-functional. Additionally, tariffs have inexplicably been unavailable on the website since yesterday, forcing me to rely on phone service for information and changes. However, each time I call, I am placed on hold and the call eventually disconnects. I have spent a total of 6 hours on the phone with 9 different representatives. The first representative informed me of a 700 euro difference in tariffs from what I originally paid, after 40 minutes of waiting. When I requested to speak to the responsible person, I was told it was impossible. Subsequent calls revealed discrepancies in tariff amounts, ranging from 17 euros to 600 euros due to alleged tariff changes every 15 minutes. Only one representative offered a solution for the call failures, promising a callback that never materialized. After hours of frustration, I finally spoke to someone who quoted a 214 euro difference, though this amount had previously been much lower. I am still on the phone, waiting to make payment, and constantly being told to wait another 15 minutes. This level of service is completely unacceptable." "I'm back to square one as the call has failed again. Despite an hour of waiting just to make a simple change and my repeated requests to acknowledge the possibility of calls dropping, I find myself calling for the 10th time today."…
