Pay-mediaventltd company that stole from your bank account, even when you never use their services Internet

This is a complaint mail to that company named Pay-mediaventltd because they stole from your bank account even when you never use their services.

I been told, when I signed up for their services: " free trial for 3 days" and now I been charged for 2 months in a row in my debit card.

Im in mexico, so I don't really know what to do for cancel that service. I just have their 800's numbers, but because I in another country this phone doesn't work here.

Please tell me what to do.

Thanks!!
