Giving a bribe if one cannot receive his right

Q: I need to know about bribe as I have heard that the giver and taker, both are sinners. But now the situation is that I cannot book my visa appointment without paying the bribe. 

I have tried every possible way to book an appointment but could not get any booking. Also I have written an email to governing bodies but there is no response on it. Should I pay the bribe and ask Allah for forgiveness, or should I leave it as is?
