Several calls from this number asking about unpaid invoice.  When I question them what the invoice is for - they don't know.  They said they're only trying to collect the unpaid invoice for VIX Co., which I've never heard of.  I ask them who is VIX, and they said it's a "service" company.

I had the same issue with this phone number calling me for unpaid invoice and asking me for my credit card number to pay, they are a bunch of scammers and they need to be stopped and shut down for good.

They said we have an unpaid invoice, and the name of the company she gave me does not exist

They keep calling my company and said we owe over $2000.00 for security and they are in Canada. We don't do business in Canada or use any services from that company. Won't give me any information at all because they don't know. Sick of these people!!!

We had been ignoring their calls since it's a foreign call center.  It's actually about Zix corp. which provides email encryption and other services.  I told them I'd contact ZIX directly, since they always email me the invoice and I know it's past due, but I won't pay a call center with a credit card.

I have received multiple calls from this number regarding "past due" email invoices; we do not, and have never used this service.

This foreigner calling asking to talk to accounts payable, my invoice is paid. I won't make a payment to no call center. I pay through Zix portal. This is not Appriver's normal number so I assume it's a scam.
