When I read its source code, I found out the url about my withdrawal request which is https://bitcoingrowthfund.com/transactions/getTransactionRequests/true

There I can see the amount of BTC, BTC wallet address, fee, status - pending, request date, something like that.(see below)
It may be there is a problem in showing that information on the homepage but actually the process are being taken place.
Please let me know when you get your coins back.
