Is DropServicing Halal? Please help me out sheikh I don't want to get haram money

asking that because I didn’t understand sheikh’s answer here

sheikh said “you should not mislead the customer to believe that you are the one who will be providing them with the service.”

but what that means

in addition to that if customer knows that there is a chance that the customer will not buy, because he will think it is better to find the original seller instead of buying from me.

I hope sheikh to give a clear and a good explination on how I can do dropservicing halal ly
