The calendar that you were using is working properly, and so is your email on your phone and in Outlook or wherever else you were using those.
Below is a CSV file of your contacts, the same ones you've edited or added in this software, which you can download and open with Excel or import into Excel. From there you can enter newer contacts to keep a record of them, or wherever else you've kept track of contacts. It's up to you to import these into whatever other app or iCloud you want to use to keep track of your contacts, on your phone or on your computer. You may have to manipulate the columns for other apps, but Excel will read all the columns that are in the CSV file.
