Alas, Yi Xun's after-sales service is really speechless. I bought an early education machine, and the sound quality of the song keys is rather confusing. I called the customer service to return it, and every time I said yes, the result was returned to me as a maintenance treatment. Finally, he told me that there was no fault and he wanted to return it to me. I communicated with customer service four times. Every time I say it's a return, I don't know how to listen. I mean, everything in the package is intact, so I can return it. I am quite disappointed in Yi Xun, which was a very unpleasant shopping experience.

Suggest the landlord to return the goods. Don't tell me that there is no label, the general recipient will not check it, or you can get the label again. If it really doesn't work, go to the website of 123 15 to complain about support.
