I never intended on keeping this Health fit App ,and the credit card I have on all my apps has declined thank God ,but I get my paycheck in 2 days.Should I remove this credit card before I have money on my card? And can I still use this same credit card on my other apps? Thank you for your answer. I need to know what I should do to cancel.I do have an old email address that it’s only allowing me to use and unfortunately it’s no longer my email address,and I don’t know password.What’s the best suggestion yall?
