Game shoddy return policy

Very unhappy with levelnof service and response. Purchased a microwave and returned because of inadequate power. Was told could not return it as it was used. How is the power to be verfied if it is not tested. According to a manager at the store, one is suppose to test it in store??? I have been a loyal Game customer but will have to review my trust in Game especially the oft marketed Game promise. Very poor and shoddy customer service. Referred matter to Bradley ( agent)_ no credible response.I would be wary of purchasing a major appliance there again.
