Somehow I have paid for the APPs (DECIBLX:dB, dBA Noise Meter). Supposedly I want to get a 3-day free trail, really don’t know I have to pay for HK$23 packed with free 3-day trial. Moreover I have tried to play with the APPs, and fond that’s not good for me. Now, I want to stop the purchasing of this APPs but I don’t find the way out. Please let me know how to stop the payment for next month.
