I text the delivery driver to let her know that I would meet her at the double doors of my building as stated in the instructions I included before checking out. I text the phone number provided but received a notice that the number was not available and to contact customer service. As I waited at the double doors, the delivery driver saw me and stopped her vehicle and asked my name. The delivery driver let me know that my order was dropped off at the leasing office and that she called the number listed but did not get an answer, then stated a woman picked up. The delivery driver proceeded to tell me that my number I provided must not be correct and for me to go online to make the changes. I am looking at my number I provided on my receipt and see that the number is just as I provided. I felt like the delivery driver was placing blame on me the customer as oppose to taking responsibility for not following the online instructions and failing to contact me to communicate if and when she arrived to hand my order to me. I deselected contactless delivery before checking out as well. When I saw that the site stated my order was delivered and I had not received it in hand from delivery driver, that really worried me as I have had orders not delivered to me or items missing in the past with Door Dash delivery drivers. This is my first time learning that Door Dash drivers are used to make deliveries. I thought an employee at business A was making the deliveries. Past negative experience with Door Dash delivery drivers is why I made my online order directly from the Business A web site instead of going through Door Dash. I will reframe from making delivery orders and choose "pick up" as an option here on out.
