Steak 'n Shake review: Not having any shake’s.

I paid on the app over 14.99 dollars for milk shakes on the app. I tried to get a refund on my money they asked me to call this number [protected]. I called that number and the person was asking me for my social security number and my card information. I said I am not giving you my social security number. That’s a red flag that there asking for that!
