I doubt the brand will survive now if I'm honest. Before all this came out not many people knew they owned Magical Day Apparel. And The people buying from them and supporting them have either been blocked, or they've cut Yaz and Ash off on principle and will never buy from them again.
If their attitude is 'give us your money, buy our stuff, support our shop, but unless you agree with us all the time, we are going to block you ' not many people will support a business like that ; let alone the people behind it.
Deleting the about me section, with the hope people won't realising that it's bring run by them, with the hopes of selling a few more shirts, before coming out and apologising for disregarding their already established loyal customers, is abit messed up to me.
Apologise and fix the relationship with those who supported you for years! Rather than forget about those lot and try and make new ones...
