Welcome to JustAnswers as this question you have is one that is quite common to our site. The answer that is given each time that a customer asks for their unique combination is that nobody from our service nor anybody online will have your combination to send to you. This is because of the safe company creating a unique combination that is only yours to have. If someone did have your combination, your safety of having your valuables in your safe would be compromised.
While not knowing what safe you own, the majority of safes asked about on our site comes from the Sentry Corporation. They will for a small fee be able to look up your unique combination that they have on-file. Follow the simple instructions here in this link:
If your safe was not produced by Sentry, then please let me know and I can look up the contact info for that particular company.
I hope that the information provided will give you the opportunity to get your safe open and used again. If you could take a moment to rate my assistance so that I know my assistance was useful and that will allow me to assist other customers such as yourself.
