I only started using doordash few weeks ago due to pandemic . I used it three times. First two times fine. Tonight was a nightmare and I will not be using them again. The website was having issues. When I finally got the order in, it went it twice and charged me for two meatball sandwiches instead of one. A bill that should have been 27 dollars was 40 dollars! I called restaurant and talked to the manager. He said he can make one sandwich but I'll need to get the credit with doordash.. that's when it became a nightmare!. I looked up customer service number. I called. They won't talk to any customers! Only to merchants. They say you have to go to chat support on website. So I went to website and had to search for awhile to even find the chat site! Then I found it. Then I waited and waited and waited and no rep came in. Then I saw an option to send an email to support in lieu of waiting. So I did that. Who knows if I'll ever hear from them. They need to credit me for that second sandwich! I'm really angry and even lost my appetite by the time the food arrived. I do not recommend using door dash if ONLY because IF you have a problem, the customer service process is so poor. In the future I will just call the restaurant and do curbside pick up. Thank you.
