I have been receiving calls from 201-793-4620 for about 2 weeks now also.
Just about the time I had carpet installed by Empire Carpet.
The caller id displays as Allsec Tech. Googling Allsec Tech reveals
Suite 300, 5 Independence way,
Princeton,New Jersey 08540, USA.
They are an indian company, Allsec Technologies Ltd. (NSE - ALLSEC), India was listed
on the National Stock Exchange (NSE) on May 9th, 2005.
I called Allsec at 201-793-4620 and spoke with a John Matthews (dubious name given the accent).
He indicated that the calls were being made by Allsec for Empire Carpet as follow up to the installation.
I told him I have been receiving the calls for 2 weeks now and everytime I answer the phone they hang up.
Interesting to note that Allsec markets the service it sells to Empire as Quality Assurance, "Allsec provides
quality assurance of voice and email service across multiple business segments...".
Sound like they're a little lacking in their own in house QA. Bottom Line - Call Empire Today and complain 800-588-2300
Call Allsec and complain.
