terrible customer service in the Columbus Indiana store

I went into the Columbus Indiana store to ask for help on a claim. I had Insurance on a phone and the guy told me that I didn't ask to speak to another employee. He stated he was only one working there he got upset that I asked to speak to someone else he said his name was Robert. He said he was the manager this happened two days ago. When you wrote his first name down he put Robert and then tore it up cussed me out and told me to leave the store said he was going to call the cops I didn't want any further problems so was just going to file complaint online and turn into the Better Bureau Business. Customer service is terrible i've been with you guys for 2 and 1/2 years on a family share plan of six phone lines two separate accounts my wife has lost her phone and we had insurance on it paying $11 a month it was a iPhone 10s I think this guy needs to be fired I will be switching companies here in the next few days can somebody please get back with me and let this be known to HR or somebody over top of the Columbus Indiana store
