Early education centers often let us buy many course packages at one time, but it is difficult to refund the money. When we went to defend our rights, we found it time-consuming and laborious, and we didn't know who to complain to. If you go to court, there will be attorney's fees, legal fees, security fees and other expenses. Because their default cost is too low, we are defending our legitimate rights and interests and cannot be cheated by these unscrupulous early education institutions. We can call the mayor's hotline 12345 or the complaint hotline of the local consumer rights protection association, and we can also protect our legitimate rights and interests with the help of media reports.
