I used the 7days trail thingy and for some reason automatically i got charged 90$ from my bank account

i really need help. i just wanted to test the vpn with the 7 days trail, i thought it will not charge me and it will just let me use it for 7 days and i can cancel it like it showed me ):Anyone know what i can do about it?

thanks

Update: i content them and they told i will get a refund soon (i hope)
Thank you all for the help!

Hi I appreciate your help, from what they said I had used the free seven days before at some point, I just got a new phone and it said I had seven days free with no warning that I had already used it before or something like that, it just charged me ):
probably my fault😓

thank u again.

Thank you very much!!
