Buying coins/diamonds

I put in request about the following and got answer to first update if I hadn't done so. I had updated the latest version of Found too. Within days it seemed another update was listed, so I updated again. I was hoping it would solve a problem with the coins I purchased but it didn't look like I got. It was just the 3.99 but I don't need to be spending any extra right now. When I updated it didn't fix anything. I am leary to delete game and reload it. I like how things are now, a little slow...a lot sometimes- but doable . I have already started over 3 times...and cannot bear to work back up to 70+ level again! Anybody had the coin issue and did you delete and reinstall game to the same level? Thanks
