Didn't recognize the number or company so I pressed the Auto Answer on my HP all-in-one so that the caller could speak with the fax modem. Company is registered as a Colorado corporation with Kirill Katalevsky listed as the Registered Agent. Originally filed with 8432 E. Long Avenue, Centennial, Colorado as the business address which, according to Arapahoe County property records, is his home address. If it gets bothersome, stop by and ask him why he's calling you.
