Purchased a 20" girls bike on 12/22/16 at 12:50PM at Toys RUs, paid extra $10.00 for store assemble, they told me it will take one to two days, and they will call me. today is 12/25/16, 3 days later, and we still haven't heard anything from Toys R us. How long does it takes to assemble a kids bike., this is very disappointing. They should assemble the bike free of charge, and refund me the assemble fee.
