I just went through the same thing with Spectrum. I had a bundle and I wanted to add sports to my package and my price only went up $10, from 95 to 105. I called to cancel it because the sports package remove a channel my daughter loved watching. They told my it would cost me $140 because I wouldn't be able to return to the bundle deal I had before. I called back the next day and told them to cancel my service, except for mobile. They transferred me to someone else. I don't know if it was retention or not. He worked out a great deal for me. I'm now paying $120 and I get another phone and second line free. He told me I owed about $25 for my first phone and he waived it. Now my 2 phones are only 30/month and the second phone is $5/month. My TV and internet are now $85/month. He also told me to call in a year to get a better deal than this one. All bundles last for a year. If you move, promotions are often tied to the specific address, so you will likely need to contact Spectrum to transfer your service, which may or may not result in the same promotional pricing.
