The buyer bought my offer but didn't provide any information about the project !

Hello everyone,

This is my 2nd sale on people per hour, the first one went smootly and the buying was very responsive. But the 2nd buyer bought my offer 2 days ago and didn't provide any information and never responded to my messages. The problem is that the delivery time is 48 hours so now I only have some hours left to complete the job, but I have nothing to work with so it is impossible.
