paypal chargeback question

alright so i sold 50m for 25 bucks. It was my first trade so i forgot to say send as gift. Any ways he charged back, but then i sent a thing to paypal with proof of me sending him money and it was refunded. Will he be able to chargeback again? becuase i don't want to spend it then go negative. Or since he did it once and i showed proof he can't do it anymore?

i hope i made sence lol

 

Only one dispute can be done per transaction, so no.

Also, asking for gifts won't cover you from chargebacks. In fact, what saved you in this case is taking as payment.

 

You lucked out, most disputes are RARELY won by the seller, just saying.
