Italian maverick Fabio Fognini has hit back at the ATP and wants an apology after he was defaulted from the Barcelona Open last week.
The 33-year-old was trailing World No.147 Bernabe Zapata Miralles 6-0, 4-4 when he clashed with the official.

Fogini was furious as he stormed off the court and confronted officials, before he smashed his racquet in disgust.
The Italian protested his innocence after the match, insisting he had been penalised for something he "didn't do".
"What happened to me was inexplicable," he told reporters.
"I'm going to investigate it. I paid for something that I didn't do."
The ATP took action against Fognini with the Italian forced to pay a 5000 Euro fine ($AUD7,800) and was docked ranking points.
Fognini threatens action against tennis body
But Fognini, who is known for his on-court antics, has slammed tennis' governing body in his appeal.
The Italian has called for an apology after he claimed the way he has been portrayed has damaged his reputation.
Fognini's racquet sponsor, Babolat, recently issued an apology for his behaviour after the Barcelona Open.
But Fognini wants an apology, or he would take legal action, from the ATP after he claimed he was remonstrating to himself.
“Money and points don’t interest me. What happened has tarnished my image, making me look like a [bad] man with my sponsors,” he said, according to Corriere Della Sera.
“I want an apology for the huge mistake. If my appeal is rejected I will put everything in the hands of the lawyer and ask the ATP for compensation for very serious damage to (my) image.’
“I’ve always admitted bulls**t, but this time I’m right and I’m going straight to the goal.”
