I purchased lifetime license of (whitesmok) software of grammar correction. However suddenly I the software stopped working and got message saying that (the license has been expired ‘ I sent many email to your technical support with no response I am very disappointed with the poor service, and am contemplating immediate corrective action. I hope that you look into the matter immediately, in case you could not correct this incident I would request to refund the excessive money I have been paying for such lifetime extended license Thank you for your co-operation, and I hope such incidents will not be repeated.
