There are two ways you could withdraw Skrill funds from Zimbabwe.
1) Through a bank which accepts SWIFT (international transfers) http://www.techzim.co.zw/2016/07/list-zimbabwean-banks-still-accepting-incoming-us-dollar-wires-personal-accounts/
open an account and you can transfer your money to a local account and join a queue like everyone else and get your bond notes
2) Using Payoneer MasterCard. You can go to their website and apply for a card. If you have the money and are receiving international payments via Skrill regularly you might opt for their expedited delivery which means you will get the card in a week. The advantage here is that you can make online purchases without the usual local bank limits provided you have the funds in your account of course.
