Block device

I bought a nova8i in January 2022on contract, on the 28th of July it got ******, I then blacklisted my device and blocked all my Sim cards, a day later it was then discovered, my husband and I went to springs mall telkom walking center to get it unlocked, they said they unlocked my Sim and should be in use soon. A day later nothing is working, we've been calling every day for assistance and all consultants keep on telling us that it's unlocked and it will work in 30 minutes, the last lady we spoke to on Wednesday night said in 24hr my device and Sim should get to work. Up until now nothing has happened yet we are still paying for the contract, all their consultants are giving false information and over promising, I don't know if we are being punished for being honest or what. I am highly disappointed in telkom and demand answers 😡
