Confirmit:Need a way out without being caught

Hi, Confirmit programmer here. I kind of made a mistake at my current job . So, I am a junior programmer at my current job, i was practicing and my test study seems to show some completes in production database . I know these are chargeable. My production database seems to have over 100 completes. If this comes to light, I will have to answer for this and might even be terminated for sure. Please help me out, is there a way I can delete all these completes without anyone noticing. Will wait for your response.

Update:: I f'ed up..after hours of no response from any programmer...out of impulse I launched the survey on new database. I am not seeing any completes in progress but administration info tab shows previous completes. I don't know what to do anymore. But I realise I'm in a deeper in this now. I need a way out.
