Ipad Scam?

Last Year I was moving and looking for internet and Was presented with the free Ipad with internet deal, the contract is now over and I keep getting notifications of autopayment failed and now overdue payments, the ipad is no longer on my account and everything I contact support, they say they do not see the ipad and to ignore the emails? I am worried these (missed payments) will affect me in a negative way, as I am now receiving debt collection text.
I've reached out to chat support 5 times and they continue to tell me account is up to date and in good standing so ignore my issues and keep trying to upsell me on a FREE apple watch..... 

I also been reading up on the Ipad scams. If you were part of this scam?, what did you do?
