Lost my FUND, i upvoted to minnowboster on 21/08/2018

On 21/08/2018, i upvoted 43.635 STEEM to Minnowbooster with my username :build7-casole, which is still unrefunded till now. Please i need an urgent answer from steemians and MB.
Am confused about what is going on or is the fund/steem lost like that.
Below is the web address i used for the upvote:
