253-753-9494 CALLED said they were a security firm, called back, its a sham no operator or sales person to contact, just a recording that said push 1 for no more calls, just kept repeating that without getting a hold of a real person.
I did a search of the caller id (L7 Srvc Call) information you posted and it came with an L7 Resources: Best Offshore RPO services and Staffing which is based in Mumbai.
I find it rather ironic considering the number these calls from overseas.
