Is it permissible to repeatedly use the free trial month to play online on Xbox without paying for the subscription, knowing that this might be considered a form of deception, and given the necessity arising from the lack of good company and suffering from idleness?

The reference for the issue of repeating free game trials is the company's system and terms and conditions. If the company permits it, there is no harm. If it prohibits it, then one must adhere to that, and it is not permissible to violate it or defraud it; based on the Prophet's (peace be upon him) saying: "Muslims are bound by their conditions, except for a condition that makes a lawful thing unlawful or an unlawful thing lawful." Idleness or the lack of good companionship is not considered a justification for defrauding the company.

It is advisable to utilize free time for what benefits one in matters of religion and worldly life, such as memorizing the Quran and Sunnah, and not to spend all one's time playing. One should also choose righteous companionship that helps in remembering and thanking Allah.
