Can't sell my DAI

Hello,
A few months ago I bought some DAI in my LOBSTR Wallet by mistake.

Under the asset page is stated: DAI was issued by the official Stellarport platform.
And under conditions: Stellarport.io promises users to buy every currency, if there are no buyers. I have had 95 DAI in a Sell order for one month now, when will Stellarport.io buy these? What are the terms and conditions for this buyback? I tried looking for it but couldn't find any info on this.

Thanks in advance.
