Terrible Customer Service trying to upgrade

I reached out to two representatives today who were not helpful or communicative. The second representative Sargavly was beyond rude. I asked for an upgrade to the $50 internet promotion and he said I would have to pay $70 for 300mbps and switch after 7 days. I asked more questions about other options as the other representative said I would have to cancel and start over to get the promotion. Once I stated the 300mbps is $40 on the website and asked which price was correct the representative said to just go into the store and ask them to help me “alright” and closed the chat on me immediately but labeled it “inactivity” so because I inquired about the price discrepancy I was pawned off to go into the store which is much more hassle and almost impossible with my work schedule. Unacceptable treatment and I have screenshots of the chat. It’s also available for download.
