Hi,
about first problem you can't do anything, it depends from administrator of website.
about second problem, simply reinstall operating system if you use computer/windows, or do factory resetting if you use android smartphone, then reinstall software/applications again.
there is no need to spend the money and try to solve problem 100 days, factory resetting is 5 minutes job and install again all your app for your android/google account.
if you think somebody can again hack your phone or computer, buy deepfreeze software and install it, I think the price is 35 USD. then no malware will be able to damage you, every time you restart computer, all additional installed things are gone., including virus and malware. you don't need to pay me any money,
bye
