I did that. There were no options, just a dialogue saying they had refunded me a couple dollars for a price mismatch. But no button to report an issue on the app or web, no chat, no email or phone number. Just a Contact Us form that I filled out and submitted with all the information nearly a month ago, and no one from GrubHub has reached out. I finally just did a chargeback a couple days ago.
I switched from Spotify because their personalized mixes and radio stations stopped letting you thumbs down songs. I got sick of hearing the exact same crap on my mixes. And no matter how many times I fucking skipped it, my metal mix would always play Mother by Danzig early in the playlist. No matter what I actually listened to, my “personalized” mixes always had the same crap on it. Thumbs down a song on a mix or radio on YT Music? It goes away forever.
