Should i delete my gigs or not

[suety21]

Hi guys help me out . I need to make a decision . I have been stuck at level 2 for like forever and i suspect its because of the negative reviews on my account . I’ve been trying so hard to get to top seller but no luck . I have two gigs that i got negative reviews for and i am wondering if i should just delete the gigs and start over fresh but that would me i would lose all the wonderful reviews or stick with it and hope that i get topseller one day?
