I had a similar experience when I changed my ISP. When I contacted Ebay they told me the only way to unsuspend my account was to click on the link they texted to me. I told them I don't own a cellphone and haven't for several years, so who did they text. I went through 6 different tech support people, and every single one told me to click on the link they texted, even though I started the conversation saying I don't own a cellphone.

You might think the stupidity stops there, but after all this frustration, I told them to delete my entire account, all my purchase history and reviews. They told me to do so they'd have to send me a text with a verification link! After 12 different techs couldn't figure out how to do so without a text verification, I finally threw in the towel.

Ironically, after a year I decided to try and log in again. Like magic, it just worked. What a shitshow...
