7-Eleven

I somehow lost ALL my rewards points when I opened the app recently. I was on maternity leave from work where I go to the 7 11. I came back and was devastated because i opened the app and there was zero points. I go at least 3-4 times a week and have been collecting my points for the last 3 years. Now I have to start all over again and I had thousands of points lost. Please help me get them back!
