I don't work for Walmart
You can, just make sure the person picking up has your order information.
One one occasion I had my son in law pick up my order, I forwarded the email saying pick up was ready and he showed that to them.
Calling would be a good plan. Download Automatic Call recorder and ask the employees name when you do call. Take it up the chain when you hit a snag. Or. Maybe CTRL+F the Terms of Use & Privacy Policy for 'order pick up' or 'added user' or 'correct synonym' 'something something'
Ur best bet would be to call
