Cramer. Block them immediately.
If you do not ship half a day after purchase, you will receive a cancellation request and defamation.
In my case, I made a purchase on Deep Night and received a cancellation request the next morning. When I cancelled the request because the item was ready to be shipped, I received a slanderous message and a threat to report to the management.
First of all, I felt a little bothered by the fact that he asked for detailed specifications, and after I asked if regular mail was OK, he said it was, so I took the package directly to the post office and sent it, but he complained that it did not arrive and said that it was strange to say that it would be sent by regular mail.
+I told him that I could change the method of delivery to tracked mail for an additional fee, but he said he would not do so and complained that I did not receive the package.
