How can I get some to answer the phone at this store. I have tried all day and they never answered. What kind of business doesn't answer their phone?

I found it's easier to go there in person then try to call them their phones don't seem to work at the business

Call 611 or use the Verizon app. They can't access your account or setup new phones unless you're there in person so there isn't much that can be done on the stores phone. Support and questions are done through corporate support at 611 or at Verizon's website.
