Is it a scam to recruit door-to-door customer service to install fixed lines?

Yes On-site customer service is a part-time job, and usually needs to work from home to provide services for the company. The company will prepare its own fixed line, and will not require the installation of fixed line when recruiting on-site customer service. Please look for regular recruitment channels for part-time recruitment such as housekeeping customer service, and don't give criminals an opportunity.
