Friendly Pajeet here.
P.S - If you AT&T is charging you more money or if you want some discount call them up or chat and threaten to disconnect. They are authorized to give you discount of up to $100.
This is for phone, tv, and internet. That's one time discount.
Or if it's verizon and you're renewing then ask then if they can add free premium channels. They can usually do one of the premium channels like HBO (whole package) for free for 12-24 months.
If it is cox beware about the router charge.
BUY the equipment instead of renting. If the equipment doesn't work you can always get a new one or get it fixed on your own.
Renting will mean that they will replace the equipment as long as it is on rent.
Always ask if there are any equipment upgrades available for free, lie about it and tell them your friend got something like that.
Don't be dicks if they say it's not available, if the agent says it's not available then it is most likely not, but they are not supposed to talk about these things proactively. It's tell unless asked.
