Refuse a refund against their terms of service
Even though their website claims a legal right of withdrawal of 14 days, when I contacted them immediately after purchase they responded that it didn't apply. Spend your money elsewhere, they are just out to get your money. "We understand your concern, but unfortunately, our Refund Policy does not cover this kind of situation. Please refer to our Terms & Conditions for more information. As much as we would love to help, we are unable to proceed with this because we are also subject to policies that do not allow us to have replacements for eSIMs that do not present any issues. We are sincerely sorry that you could not enjoy your eSIM and hope that we can turn this experience around in the future. We appreciate your understanding on this matter."
