Hi there always when I purchase gems am not getting the bonus, as example if I purchase 1100 gems I should get 200 gems by free , I made more than 8 purchases and always am not getting the bonus gems.. what I can do?!
The free gems are included in the total you buy, you don't get extra ones on top. So if you buy 1000 gems and 200 are free you are actually buying 800.
[unknown] There is no "bonus" to get on top of the gems shown. The number of gems which is irritatingly called a "bonus" here is just showing how much more gems you will get compared to buying the very first offer several times for the very same price as the higher offer. Since you are not the first one misunderstanding this "bonus", PF should really finally rename it.
