Well for me it fixed itself, during midnight I got woken by an SMS from sleep which was annoying but it was Tanki saying the payment was successful which was extremely delayed. Please fix this issue Tanki, but I got it still just in time before my double crystal card ran out :)

Recently this issue did not exist as I could buy crystals using my phone via SMS but it stopped working today even though I got sufficient credit. I don't get any reply from anything but it still charges me for the SMS fee (£0.10) which is frustrating. This has happened to me before but it fixed by itself but I want it fixed now as the paint sale is coming soon and my double crystal card is running out :( . Please help ASAP!

Isida is a great gun to use to earn massive amount of score and a great team weapon. I leveled up twice by using the great gun and it gives you many CRYSTALS! I really like Isida as it gives you a massive amount of reward and it only cost 1800 crystals!
