URL does not exist instagram addmefast

So I recently started using addmefast and I deleted the following task not knowing I couldn't bring it back ever again. I submitted a ticket on 2. 05.2016 and its already 7.05.2016 and I haven't gotten any response from their support centre. I am not a paid customer so can anyone recommend actual good sites like add me fast and what am I supposed to do? How long am I to wait? Youlikehits doesn't have insta and the rest I tried aren't effective. Someone please help me
