Dollar General review: Emotional distress

I was hired at Dollar General in 2011 as a part time cashier. I worked my way up to store manager. I've never had any write up or disciplinary action for anything. Never been late to work or closed the store early. I've been with the company for 9 years. March 2020 made 3 years as a store manager. In February 2020 my ASM was caught leaving the sages wide open with customers in the store and closing the store early. I confronted her about it and she called cooperate behind my back and started a bunch of rumors about me and another associate of mine having a relationship. ASM was transferred to another store as she stated she was working in a hostile environment. All lies. Dm came in and told me about ASM calling corporate and that an investigation was started. She informed me that said employee would more than likely have to transfer but she would let me know as soon as she found out. The next time she came in, she fired me. She never even spoke to said employee. No letter of termination or phone interview with he. Just her word that I was terminated. While waiting to hear back from my dm after her initial claim, I was contacted by two dollar General employees, one of which is a store manager, and told That the DM has been spreading rumors and telling personal information obtained in an internal investigation to other employees. This has caused me much embarrassment and emotional distress. It's just as much against code of conduct as what I have been accused of.
