Hopper review: Hopper

I booked a "Change for Any Reason" flight in May 2025 and requested a change in August 2025, in line with the booking rules. Instead of letting me choose an alternative flight, I was offered only one option that didn't suit my needs, with no further choice given.

I also incurred £40 in call charges trying to resolve this by phone, with no other way to complain afterward.

There is no other way to contact Hopper aside from spending money on phone calls.

How else can I complain?
