Debited order after cancellation

The company increased their prices few months after I joined. I wanted to cancel, the app doesn't work, you do it on the email, they tell you it's done over the phone, you call the line they tell you they are experiencing a high call volume. I am not seating with two insurance debit order while they acknowledged my email to cancel.

Do not take them, they don't make it easy to cancel. I want my money back because I have another insurance which has covered me.
