Billed for something i can't even use, and being send from pillar to post

I ordered a Samsung Note 9 as a contract upgrade on the 10th October 2018 I was told I was gonna be given a welcome pack which wireless charger; hdmi cable etc. The phone was delivered on the 15th October, when I called to claim the pack voucher wrapped on the phone I was told the welcome pack special ended at end of September. I then called telkom on the 15th October and told them that since I was deceived on our terms of agreement of this contract, I therefore cannot accept the package. They agreed and said they'll send the courier back to come and collect it. After made many days of calls the courier eventually collected the parcel on the 25th October. Remember my initial sim has since been deativated on the 15th October when the parcel was delivered untill today and on the 4th november I received a bill that includes the the new contract that I agreed with them that I can't accept just after I sent an email on the 3rd November to one of their consultant with the collection slip. Now Iam being billed for something I can't even use cause my sim was deactivated on the 15th October.
