Pay miscommunication

I recently took a new job. I had a phone interview on sep 25th and today is my first day. During the phone interview I was told my hourly pay was $12.75 but today I found out it was $11.75. Not sure what I should do... I only took this job because of the pay. I left my other job because I was gonna get paid more but now if the pay is 11.75 I won’t be getting paid more. But I also don’t want to have to quit this job. If they told me one number and it’s now different would the fix it too $12.75 or I just have to take the $11.75 or quit?? Idk who I even talk to about my pay. The phone interview was with a recruiter for the company and not a store associate
