Walmart complaint: Embarressed and Angry!

On June 2, 2022 at 18:39 I began to check out of my local Walmart store. Had over 90 items with a total of over $400.00. After having everything bagged up and loaded into my buggy I began to pay for my purchases. First of all, I paid with a Program Card of $150.00, then I began to pay with my EBT Food Stamp Card. The rest of the purchase was going to be paid with cash. Now here is the problem. My EBT Food Stamp Card is unable to be scanned. I have to enter it manually, which I done 1 week ago today at the same store! Much to my surprise I was informed that cards could no longer be entered manually by anyone, I asked since when was that the rule and was informed that it was affective a couple of months ago. I have been using this same card at the same store for months and have never had a problem until tonight!!! I had my rent money with me and but knew that I would need that money to pay my rent! I began to tell the cashier that she would have to put items back as I didn’t have the money to pay for them. There was a line behind me and heard everything going on because there was about 5 people standing there trying to help the cashier get things taken off my bill. I have NEVER been so embarressed in my life!!!!!!!!!!!!!!!!! People looking at me and shaking their heads, getting angry because I was taking so long and then the ones who ran their mouths and stormed off to another check out!!! One saying, the bitch should know how much money she has before she comes to the damn store. I did know exactly how much money I had before I came to the store is the problem!!!!!!!!!!!! Walmart was creating the problem for me!!!! So in order to stop being embarressed and stop getting people angry or upset, I used my rent money to pay for this purchase to the sum of $320.00!!!! Now, what am I suppossed to do about my rent? I know, your probably saying not our problem but it is your problem because your store created this situation for me!!!!!!!!!!!!! Now I am ashamed to show my face again in this store because of this situation. You know, it is embarressing enough to have to get Food Stamps to begin with but with all going on in the world today sometimes you have to have a little help at times. I am not a young girl with many children running behind me hanging onto my coat tail, I am not of another race or color, I am white, and I do not buy the best of anything. I buy your brand of items and for meat I buy chicken and hamburger! I get paid once a month because I am on disability and have a laughable income as it is but now to have this situation put upon me where I had to use my rent money to buy groceries, well I am just not sure how I will get that money back to pay my rent!!!!!!!!!!!!!!!!! Landlords do not wait and I am unable to work so what would you as a corporation suggest that I do to get a hurry up cash amount?????
