Law / Polish Visa Refused, Going To Make Appeal, What should I do ? [81]

My visa was rejected based on the following
1-the information provided/submitted regarding the justification for the purpose and conditions of the intended stay was not reliable
and am giving 14days to apply which i have done by email and DHL adding pictures of my wedding and also my invitee picture who was in the hospital for spinal cord operation, i send them mail and i receive a mail back indicating that they receive no such document from DHL and that i have to come in person to appeal with paying for another visa fee.

kindly advice me on what to do
