I did not even realize that I have been charged for 3 months until I checked my balance this morning! It is my worst experience ever since I went to United States this August. They did not send me confirmation e-mail telling me about any issue of auto-renewing, nor they had informed me anything of my account information. When I called them this morning they told me that only a portion of my last month's payment can be refunded. So disappointing of this company, I will never ever use this 'service' again and I will definitely suggest my friends not to do so.
