US Telecom UST Received an invoice for TELECOM MAINTENANCE AGREEMENT for $425. We are in process of changing phone service providers however we did not leave our immediate area for a provider and CERTAINLY NOT to La Verne, California

We received a $425.00 invoice from US Telecom (UST) for TELECOM MAINTENANCE AGREEMENT.  I checked the website and received a site that is currently in development. We are in processing of changing providers but we remained with a local company.  We certainly did NOT go to a service provider in California.  Not certain if they have access to activity with our previous provider or our new provider that would have initiated this scam to be directed to us.  Whatever the case, it is NOT legitimate.
