There are roughly five types of calligraphy fonts, which conform to certain stroke characteristics. Whoever wrote it is called one of these fonts. For example, your handwriting is a type of running.
Computer fonts only appeared in the last twenty years. Professional font companies develop specific fonts according to market demand. For example, on the computer, there are boldface, song style, imitation song, running script and so on. The running script here, especially the running script written by the calligrapher Ren Zheng, is the running script on the computer. Not every calligraphy has a computer font, it depends on whether the font company is willing to make it into a computer font. Your handwriting has no computer font.
So the customer service is talking about the running script in the sense of calligraphy font, and you are talking about the running script in the sense of computer font. Of course not.
