FNB DEVICE

I have bought cellphone device from FNB, on the 22 January I have called FNB guru as the device was giving issues and I was told that it was OBF.I then cancelled the contract and I was told that they will come and collect the device from me.its been 2 weeks now, the device have not been collected from me and no one have contacted me to collect this device. I have called fnb on the 26 Jan 2016 and spoke to Prishen and she told me that they will collect the phone on the 29 Jan 2016 from me and no one collect the phone or called me.I called the FNB Guru again on the 29 Jan 2016 afternoon lucky I got through to Prishen again she told me that she was sorry she does not know why the phone was not collected from me.she told me that she will contact me on the 2 February 2016 to arrange that the phone get collected from me on the 5 February 2016.she did not contact me to date. This is pathetic from professional company like FNB, if you make commitment to someone keep it, if you promise to call do so.PLEASE COME AND COLLECT YOUR DEVICE,I DONT HAVE INSURANCE FOR THIS DEVICE IF SOMETHING HAPPENS TO IT.
