Scam- Never received credits as promised – Dingtone: Phone Calls + Texts Review

I continue to waste money on this app and have completed apps on multiple occasions without receiving credit. It seems Dingtone only gives credit when under 20. I am still waiting for DealDash and Inbox Survey totaling 1,216 credits. :( Don’t waste your time! Edit: Thanks developer for your reply. Unfortunately, I had not previously installed either Deal Dash, or Inbox Survey. It has been several days and no reply from either sponsor. I did follow your chain of command as requested. NADA! Very disappointing. Perhaps there are other credible phone apps out there. I can not recommend this app.
