They were contracted through BestBuy to look at my dryer that was making noise. They cancelled my appointment twice without alerting BestBuy or myself because they didn t receive the serial number to my dryer. Claimed they wanted the serial number before coming out so they could order repair parts ahead of time. How can you order repair parts prior to knowing what the cause of the noise is? Worst customer service experience ever. Do not recommend and would give zero star review if that was an option.
