Need to keep internet and mobile but downgrade TV and Phone

My contract was up in Jan so I dutifully tried to get a new contract with online rep. I was constantly quoted lower rates  and 4 service discounts for about $210/Mm. Bill didn't change. I tried again and was told it was going to be fixed and quote was correct. Ultimately I was billed for $279. So began another round of chats with reps who said the would fix my bill but that the quote from original rep was incorrect and my monthly bill would be $232. I've already turned in all of my boxes to try to reduce costs. This bill is still to high and now I'd like to downgrade my account to mobile and internet but unable to do that manually on the site. I've gotten so much misinformation about what things actually costs I don't think I believe the reps anymore. Is the someone from customer service who can give me an accurate representation of costs and help me reduce my bill. Thank you
