Pop Candy brand wrong sizes

Firstly the "pop candy" is so wrong for mostly their sizing. They just plug a 3-4years on a t-shirt small enough to be that of a 1 year old. It is such an inconvenience because you may need to use the product as soon as tomorrow and the admin of logging returns might take another couple of days. I bought the kiddies shoes and women slippers, the worst or rather wrong sizing. I will no longer buying this brand there. Superbalist please do something about this.
