Looking for one of these

Hi, I am in desperate need of one of these adapters. If anyone has one??? I will buy it from you!

Still waiting on response about issue with my adaptor

I have put in 2 requests for help to do with my capsule not being able to fit the adaptor even though on the website it states it should be able to fit??
A reply would be great to do with my case that was lodged.

Hi Jaymie, we do sincerely apologise for our delayed response to you.

I do see however our team has been in contact with you regarding the adaptor you purchased.

We hope you can now continue to enjoy your outdoor adventures with Mountain Buggy® with your little one. We're always continuously working to improve our brand experience with our amazing customers & absolutely appreciate the constructive feedback of where we can improve - we take your review and experience on board.

Thank you
