Walmart Email Verification Error Prevents Delivery Orders

For more than a week now I have been unable to place any delivery orders on my Walmart account, either through the app or the website. My account appears to have two email addresses attached to it, and the extra, unused email is blocking me from being able to verify my account and complete any orders. When I go into my account settings and try to change the email to my correct address, which is tab2***@aol.com, I receive an error stating that there is already an account with that email. Because of this conflict, I cannot fix my own profile and I am locked out of ordering. During this time I tried to place an important delivery order, but it could not be processed due to this problem, and now the items I needed are out of stock. I have already spoken with four different agents and a supervisor about this issue, yet no one has been able to resolve it or remove the wrong email from my account. I live in Fairless Hills, PA 19030, and I rely on Walmart delivery, so this ongoing access problem is very frustrating and disruptive. I request that the incorrect email address on my Walmart account be removed immediately, that my correct email address be set and verified as the only email on my account, and that my full ability to place delivery orders be restored without further delay. In addition, since I lost the opportunity to purchase needed items that are now out of stock due to this account issue, I am asking you to review this situation and offer appropriate compensation for the inconvenience and lost order.
