Contract device never received

I app**** for a contract phone via mtn on the 2nd of June 2023 and on the 8th of June 2023 dsv came to deliver the device and for some odd reasons the biometrics failed and they had to return with the device fast forward to today I still haven't gotten any device,I requested for a cancelation and one of thier agents called and convinced me otherwise and I gave them a second chance to deliver the device fast forward to the day of delivery and they didn't pitch,I called dsv to ask about my delivery and guess what mtn told them to hold on with the delivery but in the morning of the supposed delivery I got an sms stating that my delivery is underway. I called mtn and mondo but I'm not getting any help. I just want this thing to be canceled so that I can move on because the contract is hanging on my name even though I haven't even received the device. To anyone looking into getting a contract via mondo PLEASE DO NOT, one of their agents was even shouting at me because I wanted to cancel the whole thing and get over with it. It is so frustrating because no one is willing to help. Save your money and time and go elsewhere.
