Very Bad Internship Experience Spring 2018 - Social Media Coordinator Life is Beautiful Employee Review

I did an internship during the Spring of 2018 and no one was helpful or tried to teach me what they did. At the end of my internship I asked if they were looking for full-time and they said they were only looking for people related with graphics. I went home and saw on their LinkedIn that there were 3 job postings related to Marketing and Social Media. Atleast tell me the reason and don't lie.
