No client service

I ordered a new line from vodacom on 24 November 2017. I was contacted on Friday 1 December and was informed that I will receive my order on Tuesday 5 December. When I phoned to follow up I was told that I was not going to receive my order and that the phones i ordered was actually on back order. I understand that these things happen, however the way it was handled and that the person phoning on friday to inform me of delivery actually informed me that i will be receiving the goods and when I phoned back the person I spoke to actually just said well sorry it is on back order and there is no way she can help me in how long it will take for delivery. It was really unprofessional to give me wrong information in the first place and when asked to assist there was only said there is nothing vodacom can do I will have to wait they dont know how long. Check my previous ratings on the system it has always been bad. I have many contracts but dont know for how long I will stay with vodacom.
