Its my first time rating today on playstore cause the app is freaking buggy i sent a lot of appointment and i didnt went through and the staff at wall greens nor customer swrvices wasn't able to help with the situation and gave me an appoinment even though i have video evidence. And they should still have appointment available in person not alway online. So in total I waited for 2 hours just to be able to set an appointment and its a different matter to get the booster i waited for long time
