FRAUD! I cancelled my Grammarly trial in March and still received a charge on next June! My mistake was to leave my credit card number on their web site.
There is no support line to call, the number *******146 is only a recording with references to the web site. I left several messages on their web site without any reply from them.
I am now trying to dispute the charge with the credit card. But in the meantime I am out $135 USD from fraud
