Still no response from Vodacom

I find it absolutely pathetic that after two days that I have logged a complaint, nobody has called me.... below is my original complaint.

Good day, I wish to express my distaste and bad customer experience. last week Vodacom (or a subsidiary ) phoned me and ASKED me if I am interested in a data bundle router of 5gb daytime and 5gb nightime for about R200.00 I agreed to it and the agent said it should be delivered today (Monday 16 October 2017). I went on to phone Vodacom and just track my order and confirm my details again due to past experiences. I was then told that the router from the supplier is on back order and it will take me now an addiotional +- two weeks to receive my router. I find this distasteful as how can an agent create an expectation and sell me a product and then tell me it should take a week only to find out it will take now an additional two weeks due to a back order. I promise this to you, if the agent had known about the back order and informed me or any other customers accordingly, I would not have an issue. So either the agent withheld information from me to do a sale or the agent was uninformed either way. And if the stock shortage occurred during the course of last week why wasn't I informed. Must clients first complain before a response before attention is given or don't you think it is better to inform clients upfront. I'm looking forward to your response. warm regards ,
