Vodacom cannot commit to service nor communication

I placed and order for the Iphone 5s special at the Vodashop Gateway on the 8 January. I was told the stock would be in by 1 Febuary and I could come in. Luckily I called firat as they did not jave stock nor do they to date have stock or are able to accomodate me. I was never called by Rochelle Robin mor the manager as promised and left several messages on severl occasions that were not returned. I took this up with headoffice who also promised to get back to me and escalate the issue and have also yet to actually do something constructive to resolve this issue! Their turnaround period is supposed to be 24 hours yet that commitment promise was broken too.. utterly disgusted! Absolutelly no service at all! Why do cuatomers always have to resort to posting on such a sight in the hope of a reaponse and resolution. This store continually doea not have stock yet others do. We were also promised covers by the manager in apology for initial bad service and so decided to stay with that store for the order but at what cost?
