Horrible Agent - Bad Customer Service

Can you guys please train your agents to stop bickering and escalating conversations? 

I had an agent mock me and belittle me when I requested wireless internet 

my unit does not have any coax cables no modem to connect a router there’s no phone jacks or WAN onsite I need wireless internet 

the agent mocked me and said there’s no such thing as wireless routers 

I explained that I understand a power source is needed but again I have no coax cables to connect a router too

t-mobile has wireless internet I’ll just cancel my internet and xfinity mobile and go over to T-Mobile at this point 

I even asked the agent to transfer me to the supervisor he refused to and kept asking why and how he was being rude and I told him his supervisor can listen to the call together with him and review it and go over that with him and explain it to him. 

the agent then threw me into a random queue 

and now here I wait for over 10 minutes trying to get answers
