NCT class cost warning!

So I was very excited to be booking on to a baby massage class with NCT. Bare in mind I am being very prepared and haven’t actually had my baby yet. I booked in for baby massage for January 2020 and paid £50 for this course, however discovered there was a sooner class in November 2019 which would seem more appropriate and better for me and my baby as by January my baby will be moving about and probably less keen to lay still to be massaged. I emailed within 2 days of realising this and asked if I could transfer class and seeing as I have been organised and booked 8 months ahead I didn’t think this would be too problematic! However NCT policy is that to transfer course will cost £25 and to cancel it will cost £30! Completely understand if this was last minute or even 4-6 weeks before a course starting. So disappointed about this, especially being the first thing I have booked and planned for my baby. Anyone booking on to NCT courses - make sure you are picking the right course and right date because you will be charged a ridiculous price to cancel or change regardless of how far in advance you book! A complete money making scam to charge that amount.
