Query: The pedaling chain slips

I am not happy with this toy as it is defective. Upon arrival, the pedaling chain slipped out of its bracket every 10 feet. After calling customer service, we were advised to take the toy bottom off and adjust the chain bracket. We actually had to bend the metal parts of the bracket to hold the chain in place. I do not recommend this toy until the defects are fixed.
