During the recent period, many customers who bought PINING magic mop called to request after-sales service and maintenance. The customer service staff asked them where they made the purchase. The customers replied "TV shopping", "Taobao", "online shopping mall" etc. According to the survey, all of them requested spare parts replacement. At first, we replaced the parts for them and they expressed their thanks one by one. However, there was no record in our factory and they did not make the purchase from us. So it is unnecessary for us to be responsible for the after-sales service of others. Why should we allocate the parts?
