My phone got lost in October 2015, I only received a replacement phone January 2016. Not only that it took almost 3 months to replace my phone, but I was given a faulty, used phone which keeps on switching itself off, that phone is second hand, it either went for repairs and came back or it had a manufacturing fault,the box was opened when I collected the phone.<br> The reason why it took them 3 months to give me my replacement was that it was discontinued and they could not find a phone like that anywhere, to my surprise, their Roodepoort branch had a repaired used unit, which was issued to me.<br> I want to state it clearly that I did not insure a second hand phone and that the store will be forced to look for a brand new phone for me and give it to me so that I can return this thing that they gave me, I will not rest until this matter is resolved and the phone that I want must be a sealed Blackberry (with buttons),it is not my fault that the company wanted to make profit *******ly from me by making me pay insurance and discontinue my replacement during the contra
