A 37-year-old Toronto woman is suing telecom giant Rogers Communications for $600,000, alleging the company's billing practices revealed her infidelity, leading her husband to leave her.

"I had a brief affair -- it was very short-lived, a few weeks," Gabriella Nagy told CTV News. "I did not need to lose everything. I am at a point that there's no turning back. Everything that I held dear -- especially my job -- is gone."

Nagy filed a statement of claim alleging an invasion of privacy and breach of contract on Roger's part in an Ontario court.

Nagy had a cellphone account with Rogers in 2007, in which a monthly bill was sent to her home address in her maiden name. Her husband, who is not named in the statement of claim, had the family's cable and TV bill under his name.

In June of 2007, he called to add Internet and home phone services and the following month Rogers sent a "global" bill to the home address, including the itemized phone bill for Nagy's cellphone.

The husband saw several long phone calls to a single phone number, and called the number, and a "third party" revealed an affair on the part of Nagy, the woman told the Star.

"The husband used the previously private and confidential information that the defendant unilaterally disclosed to the husband to inquire about the people that the plaintiff was telephoning and the nature of such calls," the statement of claim reads.

The statement alleges Rogers "unilaterally terminated its cellular contract with the plaintiff that had been in her maiden name and included it in the husband's account that was under his surname.

"The plaintiff's maiden name and the husband's surname were different. Such unilateral action by the defendant was done without the knowledge, information, belief, acquiescence or approval of the plaintiff."

Rogers says it cannot be held responsible for the breakup of the marriage or the effects on Nagy's life.

"Rogers is not the cause of these," the statement of defence reads. "The marriage breakup and its effects happened, or alternatively would have happened, regardless of the form in which the plaintiff and her husband received their invoices for Rogers services in July 2007."

Nagy said her husband walked out on her and their two children after the affair came to light.

She says she was so upset about her marriage falling apart that her work performance suffered, leading her to lose her job as an apartment rental agent that paid nearly $100,000 a year.
