Don’t buy from Toys R us

Very disappointing!!! My son saved for months to buy the shox drone in the beginning of October 2018. He flew exactly twice with the drone. Third time it started giving problems. Did not want to go up. Took it back and I was told that it is past 30 days. Now my question....when one buys such an expensive item one trusts and believes it would last and not hear it is past 30 days. Now I’m sitting with a boy extremely disappointed and a drone not working and staff unwilling to assist
