I'm sorry, something is going on if in 24 hrs you received 3 negative feedback. You do not deserve them all changed to 4 star.
As stated, for the next 90 days, we will only change to neutral even if the buyer requests 4 star.
I understand the point you made, I truly apologize for the inconvenience I have made over the past 24 hours.

I just think this could be a case-to-case situation.
1. First negative feedback was received due to my own mistake, I sent the buyer the wrong products, but I have resolved and satisfied the buyer. Since we couldn't remove the feedback I asked the buyer to change it to 4 stars.
2. Second negative feedback was really a scam by the buyer. The code I sent to the buyer was tested before being delivered. The buyer only has one negative feedback on the profile related to previous fraudulent transactions. Nevertheless, I still offered the buyer a brand new account to keep him satisfied.
3. Third negative feedback was left without a transaction, was from a potential buyer. The potential buyer consulted with me through discord regarding one of the combo and left me negative feedback because I was not responding quickly enough (We have time conflicts.) Later I have satisfied the potential buyer with a huge discount.
I totally agree that I have hit the jackpot with receiving 3 negative feedback within 24 hours. The last time I asked to removed/change feedback was back on October 4 of 2020. I think the third negative feedback deserves to be removed, because “Feedback can only be given if a sale has begun. This means either payment was made or the item was given.”
