Crease in new beginner board

Hi guys,
Need your advice. Just bought my first fiberglass board last week, and already had a lot of fun on it in the first two sessions. However, after last session I noticed two little cracks at both rails towards the tail. Later on I saw there was also a crease in between at the deck.
Really bummed about this happening after a week already, probably happened in a wipe out... What would your advice be to do, get it repaired completely or only fix the cracks at the rails? I bought the board for 400 AUD new.
