Well, in fact, I find something makes me misunderstand this month. You see, when I check my mobile payment list, July's cost is more than twice as past times. 112 dollars more. Thus I'd like to ask the reasons of that, because I did not call anybody, ask any new services, etc. Well, I'm waiting for the answers, but do not call me directly. It is better to send an email to my address, which you are able to find in my account data. Thanks for your help.
