Years ago a company I worked for used a Verizon reseller so they wouldn’t have to deal with the seemingly endless non-service related issues. Great signal/service but atrocious sales and customer service even for business accounts. We paid a premium on top of a premium just so we didn’t have to deal Verizon’s sales/support directly. I doubt it was the best financial decision but being able to get a replacement phone delivered same day/next morning with no questions asked, having billing problems dealt with quickly or issues with the definition of unlimited sorted out in minutes was amazing.

That was years ago though so things may be different now.
