Order cancel by a seller

[kekeli1]

I introduced a friend to Fieverr and she was disappointed by the the seller two times. the first one the guy promise to do the work when it was left with a day to deliver, my friend just realised that she cannot contact the seller anymore and fiverr did not refund her all her money.

She contacted another seller who promised to do a good job and he ask for a period of two weeks to complete the job , this new seller asked for an extensions of 3 days after the delivery date is past , the extensions was granted by the buyer. To the surprised of the buyer the seller asked the buyer to cancel the order because he is not in position to do the work. Now my friend feels so disappointed and does not know what what to do. what can fiverr do to save the situation. I seriously need your help because my friend is let down. please help
