momentum multiply travel desk_horrible service

I pay a monthly fee for a family profile with momentum multiply so my family can benefit from the programma on things such as discounted domestic flights. However on trying to book a flight for my daughter who is travelling with my sister, I was not able to. I called momentum for assistance who first cud not assist an when requested for a manager, was then provided a solution that meant booking my kid as an adult and claiming a refund from them, heres the problem u cant book a flight for a kid as an adult on mangos website. Thanks for the awesome solution momentum muliply travel desk! Frustrated!!
