Walmart complaint: No help with a possible fraud issue

I keep getting text message about there being substitutions on my order or that my order is available for curbside pickup. I never placed any order!I called the customer service number, and I could not understand anyone!
I have hearing problems and they all have heavy accents and do not speak English well. Why do I have to come off as a racist and an ugly American because you will not hire anyone in the United States?
Your customer service agents are also rude and very combative. I tried using the chat and a guy named Joseph was not helpful at all. He would not read my messages and was trying to get me to close my account. Is that what Walmart wants? Close the account rather than helping people?
I am very disappointed in the way that Walmart treats their customers. I am DISGUSTED in the way that Walmart discriminates against the disabled! You should be ashamed in yourselves!!!!
