Don't tell me this is persistent education. I have been waiting for more than a month for the math education textbook I applied for. Finally, I said that I didn't find any online teaching form. There is only one textbook for my nine courses. I want a refund now. They say they can get a full refund within three days, and then they will deduct a part. I paid a total of 1800 yuan to me. After dropping 700 yuan, he said it was a discount in Qinghai, and no refund was allowed in other places. After submitting the refund application, they said it would take a month to return it. It is still a question whether the money can be paid now. Never report it.
