F-bombs rained on ETrade when an irate Queens man swamped their customer-service reps with 7,000 profane phone calls in three months, according to a lawsuit.

Abrash Fuzaylov “terrorized” the online investment company’s employees, “regularly and repeatedly spewing profanities, requesting sexual favors from ETrade’s female employees and directing homophobic slurs to ETrade’s male employees,” according to a Manhattan Supreme Court lawsuit.

The calls have caused “massive internal disruption” at ETrade, where “innumerable” workers have threatened to quit, the company claims in court papers seeking an order barring Fuzaylov from further calls.

Fuzaylov was an ETrade customer for a decade before he complained about $1,000 worth of fraudulent transactions on the debit card connected to his account.

ETrade settled the dispute with an $1,100 payment and closed his account, but Fuzaylov lost it in February when he realized the money was taxed, the company charges.

He was so angry when ETrade declined to pick up the tax bill, he allegedly started his filthy phone campaign, at times using more than 50 different numbers. Fuzaylov could not be reached.
