PAYMENT

Hello guyz!! I am from India..I want to buy the 170 teacups package in RC...before I have bought 5 teacups package quite a few times and 1 time 15 teacups package..but I really want to buy the most pricey one this time..but I am scared as well..Is the payment process safe? And the app won't glitch or anything, right? I will be buying using the same process I have used before for the smaller packages
