u/Effective_Mark_1334

I'm traveling to the UK for a business trip and was told I'd need to get an ETA. I clicked on the first thing that popped up (my mistake) and did it quickly without checking. I was told it'd cost around 25e, but it ended up costing around 140e.

I just got an e-mail from the service saying I'd need to add further information to process my ETA. My question is, can the service sue me or something if I don't pay (I transfered the money from my bank account)? I'd really love to keep the 100e.

Thanks in advance for any help.
