Do I really want them to have specific time to reimburse those who invest below the minimum, or is it not important to them?
What's the minimum ?
0.1 BTC or ETH equivalent was the minimum contribution during the token sale. If you had invested above the minimum contribution, you will get your tokens, if not, the contribution will be refunded (unless it's more than 0.05 BTC, which is their changed minimum contribution and in that case you'll get your tokens.
When will I get back money, they are late
