Most certainly did complete the learning paths. No one has come forward to say that they have received the voucher. That should tell you everything

I did. Still I didn't get it. Did you?

No I haven't done the learning courses nor did I get the voucher as zindi has said that all participants get the voucher if they made a valid entry

There were other learning modules that were part of the challenge so i didn't think it was an efficient use of time
