if your going to casually bot on 1 acount just bot on your own ip , but for farms ( to avoid mass bans or ip bans ) you should use proxys.
and for where you should buy them i would say @D Bolter
are you using proxys for the accounts and login to your own ip ( maybe accidently )
its more common than you would think normally , but its annoying for sure
there is no-one scamming your money here .
are you looking on the correct paypal account ?
go to settings -> payments -> view ''your automatic payments'' -> select the monthly subsription -> cancel
easy as that
