CONTACT DETAILS

I took out a black friday deal on the app, i have been trying to amend my details all week since Monday 27 November, its the end of the business week and no one in FNB can assist me, not even the FNB connect team. I am getting messages stating that I will need to pay cancellation fees, however no one is attending to my request, not on the app nor over the phone. Please can someone contact me. i want my phone and the deal, I have spent over 20mins on the phone all at my costs and still no help yet again
