I'm replacing an alternator in my car, found the one I want at a good price with a good shipping date on carparts.com. Came here to read reviews, make sure it was a legit supplier, most people had good things to say.

TL;DR - their phone number isn't active, their chatbot gave me a number to another company, and the email response seems to be from a chatbot that doesn't understand what a core charge is.

Almost instantly after placing my order, I got an email saying the alternator I bought is out of stock. Soon after, I got an email saying the rest of my order has shipped. The tracking email is confusing, looks like it might include the alternator, so I wanted to confirm what was shipped before ordering from elsewhere.

The chat bot couldn't tell me anything useful so I asked to speak to a real person. It gave me a phone number to a different auto parts company. I called the number on the website, but it's not in service. I emailed the customer service address. The response said: "Unfortunately, one of the alternators (NP2104303) was deleted from your order shortly after it was placed, so it won't be shipped. However, the other alternator (NP2104303_CORE) is still being processed and is expected to be shipped soon."

It's common for an alternator to have two line items, the main cost and the core charge, I assume so they can refund one item (core charge) when you return the core. So either the person responding to my email doesn't know how this works, or it's a chatbot response. I'm worried they are shipping me an empty box and charging me $90.

I replied to the email and asked for clarification. No response within a few hours so I emailed again and asked them to cancel my order and refund my payment. With no available phone number, I'm not sure what else to do to get my money back. Any suggestions? Call my credit card company?
