EasyJet - no seats left to have children next to adults

Help please!

As the title suggests, I went to check in for a recently booked flight, travelling in two weeks time. There is no possibility anywhere on the plane to have children (7&4 years old) sat next to either adult travelling (4 person trip in total) due to the fact the plane is 95% pre-booked seating already. We have selected and paid for the best alternative seating, spread over 2 rows and accross the aisle but it’s not seating we want to travel in.

Customer service have been rather unhelpful and advised they can’t move other peoples seats, but they have said the airline staff at the airport will be able to find seats for you on the day and that they guarantee each child will be sat next to an adult. I am sceptical of this and my better half is obviously nervous about leaving this to the day to resolve.

Has anyone had any similar experiences in the past or insight they can share about whether this is likely to happen?

The only Alternative option I can see is booking another flight on a different airline and losing our money.

Thanks in advance!
