Why did Shenzhen Schiller Trading Co., Ltd. deduct the money from my bank card?

Negotiate first, if negotiation fails, call the police.

You can directly find the customer service of Tenpay and tell him this situation. If Tenpay automatically deducts money from your bank card for no reason, he will pay it back. If not, you can't deduct money for no reason, and you should give a reasonable explanation. Another reason may be that someone else has stolen your Tenpay account. You can change your password or contact customer service. It is recommended to turn off express payment and check whether there is a Trojan horse on your computer or mobile phone.
