Apple Watch scammed

Fell for your scam with the “free Apple Watch”. Upgraded a device on my mobile plan over the phone today, and at the end the rep pressured me into claiming a “free Apple Watch” for my 2 lines. I told him I don’t want to pay any monthly fee, what’s the catch? He says no catch they’re completely free, just ignore the initial $20 a month charge and don’t activate the watches to cellular service when they arrive. Hesitantly I said ok. 
immediately after I started doing research and apparently this is a common scam you guys have been doing for years. And if I don’t activate my watches to cellular I’ll be charged the $300 device fee (per device, I was slotted 2) or I have to by the $26 a month for 2 watches
