Appalling online booking and check-in system. Some parts don't work on the mobile app, others on a phone browser, others on a computer browser. Booked and paid for baggage. After about an hour trying to check in, system said I had not paid for any baggage.
After receiving my boarding cards, I thought I would check to see how much a business upgrade would have cost, but didn't purchase it as I was just curious.
On arrival at TFS airport, a gruff manager checked and told me that my baggage purchase was in the system but that I still had to pay for my upgrade. I explained (in Spanish, I'm a translator) what I'd done and said I didn't want it, I already had my boarding cards. She told me those were no longer valid and I would have to go through check-in again. I asked how it was possible to be issued boarding cards if I hadn't checked it. She just shrugged and walked off.
As the check-in queue was painfully slow I decided I would just go with the upgrade, very begrudgingly, as I could go straight to the business class desk, time was passing, and it would just be easier at this point. I paid for the upgrade and received my boarding cards.
As I passed the manager, she started talking to the check-in assistant about me, in front of me, asking why she had checked me in because "I thought he said he didn't want it". I asked her if there was a problem. She said I hadn't told her that I had changed my mind; I asked why I needed to explain anything to her if I had just paid for the upgrade and been issued my boarding cards.
However on arriving at security, I noticed that I had been issued economy boarding cards despite paying for the upgrade, and had to go back to the check-in desk and wait for another 15 minutes to get my correct cards.
Dreadful, unprofessional, discourteous service.
