My service

I had been a loyal customer for years. Before I moved, I had requested to change my service location which seemed fine. When I moved my modem did not work. I contacted customer service and was informed of a new plan that was much leas expensive and included double the speed and an iPad. After giving personal information to secure and a payment of $75, they then decided to send a technician to figure out my internet. I confirmed multiple times what my monthly payment would be, with no added charges. The technician arrived and helped with my internet. I received the iPad , but I saw they added a SIM card that said it would be an extra $20 a month. When I contacted customer support, the online agent mentioned my account was inactive. I was on the internet at the time. They also mentioned there was no such service as a $60 a month service. I asked them to confirm with the previous transcript. The agent said he would check, but then left the chat. I cannot get a hold of a human on the phone. I am close to closing all accounts.
