False promises and constant lies

On the 6 of April 2015 .. We went to vodacom the glen to get a LTE. We sat down with a young man .And asked if we can please sign a contract for the portable wifi LTE . He was more than happy to help us . Once everything was signed .. He informed us that they don't have stock .But they will have stock on the Monday .On the Monday I drove past there and he did not have stock . He said I must come on the Thursday .. Same thing .He then told me the following week it will be in and he will contact me .So I decided to wait for him to contact me .That whole week I wasn't contacted .I went in on the Monday and spoke to the young man .. And asked what type of service is he providing . Never have we had a problem with vodacom .So now y the sudden problems. So I asked him to please call me at least once in the week to let me know what us happening . So once a week he called me to inform me there is no news yet .. Last week Friday I went in to speak to the young man and saw that the LTE router is now available. So I asked is that in stock . He told me no. But the warehouse has . And by Monday he will have it and call me . I went past there today and still NOTHING . Vodacom the glen is useles
