2 non existent ''delivery'' attempts. :(

Tracking for a OneDayOnly order shows (ODOJF***S1) was received by FnF on 2020/05/04. Between then and today they've recorded "NOT AVAILABLE'' on 2 delivery ''attempts'', one on 05/07 and another on 05/08. I did not miss a single call on those 2 days if the delivery guy was lost, i'd be as bold as to say there were no delivery attempts. Please may i have my parcel!!!
