房客，男，单身。上个月开始就拖欠房租，打电话问了以后，说是事故受伤，回新加坡父母家里修养，上个月月底勉强把房租付了，这个月又拖欠。
我不清楚他是否撒谎（因为有撒谎的历史），感觉诡异，所以昨天给他发信说因为他不在家，怕家里漏水，今天要上门去看一下。
这之前给他邮件短信一直没反应的，收到我上门的邮件后，立马给我发了一个邮件， have just forwarded an email from Enbridge Gas detailing a Category "B" Safety Violation at the mentioned address. According to Enbridge, the gas service has been temporarily discontinued due to unaddressed safety concerns identified during their recent inspection. The email outlines the necessary steps to rectify the issue and have the gas service reinstated.
Given the urgency of the situation and the absence of gas in the apartment, I kindly request your assistance in arranging for a certified natural gas technician to address the noted safety violations as soon as possible. This is crucial not only for the reinstatement of the gas service but also to ensure the safety and well-being of the residents.
下面是他附件的主要内容。我的问题是：
1. 有谁知道这是什么问题吗？原因是什么？
2. enbridge公司给他发warning的时候就是在他收到我email的那一刻，enbridge公司周末晚上是不上班的，我感觉是他去网上下载的，这里面有什么猫腻吗？
3. 我应该怎么做呢？给enbridge打电话，他们要刀周一才有人接听。急等各位建议，谢谢
