Walmart complaint: discrimination and harrassment

I, Charles Robertson, came into Walmart on 682021 at approximately 1:00 pm, to get a few items. After checking out my merchandise from the self checkout lane, i continued to walk out the store when i was stopped by the door host by the name of willie. So, i noticed that i got the wrong brand of water so i went back and traded the brand of water for the right one. So, after checking out the water for the second time, Willie had stopped me for the second time and and in the process, i couldnt help but noticed that he let two white people go out the door before me without stopping them when they had a big thing of toilet paper that was not in bags. Willie singled me out and asked to see my receipts. So, i asked him wait a minute, why did you let them go out without stopping them and their items wasnt in bags but yet you stopped me for the second time. and Willie stated that aint nobody perfect. At that point i felt humiliated and embarrassed and i was discriminated against because of my color and was harrassed. Why did he stopped me and not the white people? He should have stopped everyone who didnt have items in their bags. So, an off duty employee had stopped and asked what was going on and i explained to her and she then told me to ask for a manger because we dont tolerate that. After that point, i asked for a manger. Then the assistant manger Jerry Orange and the manager Rebecca Chatham approached the situation and that when i explained to them of what had happened and thats when Rebecca Chatham said we will handle this and i stated no, i need to file a complaint against this incident right now and then the assistant manager Jerry Orange gave me a 1800 walmart number to file a complaint. As i was walking out toward the door, Willie stated that he was sorry. So, that same day i called that number and i spoke with someone in the complaint department and she took my statement and gave me a reference number and she connected with the ethics department and i spoke with someone there and they told me that they would get back with me in 4-6 business days in which they did not. So, i called the complaint department for the second and third time and they are now telling me that the reference number that was given to me is not in their system and they are not returning my calls. And i feel that the complaint department and ethics department intentionally failed to respond to back to me involving this situation and brushed it under the rug. As of today, i still feel emotionally mentally disturbed ,discriminated, and harrassed behind this.
