Random negative feedback

[Mac55watson]

Hi,
I have recieved a random negative feedback here is the link
https://www.epicnpc.com/itrader_detail.php?ir=559639&u=413825
I have made no sales in last few days, only 1 sale since start of april tbh because i have been giving exams, imjust became active 2 weeks back and did a sale.
I have no idea who this person is and why he left this feedback,
Please resolve this, thanks
