Mystery Bag Refund

I bought the Buzzy Garden mystery bag during the door busters sale because I was excited for the bag and the contents (I lean into florals) and I just received notification of a refund. I received everything else from my order and knew they hadn't sent the bag which wasn't a surprise to me, as it has happened before.

I appreciate that they gave the refund to me so quickly, but I am wondering if anyone knows why? There wasn't an explanation in the email other than they were refunding me.

Not upset, just curious if anyone else got a refund or knows what happened.
