When I worked for a bank call center the first question before initiating the dispute/chargeback process is “did you attempt to resolve this with the merchant first?” It is a requirement for doing the dispute. OP needs to clearly say yes, and they prevent it by not letting me speak to a human.
OP should also file a police report immediately. They won’t care, but at least the store can’t accuse OP of not following properof procedures.
Walmart has Spark which is a delivery network they control that’s similar to door dash but AFAIK doesn’t require any logos on the vehicles.
