MTN - POOR SERVICE

We have been trying since 11/01/16 to obtain 2 new contracts from MTN, for business purposes. I firstly contacted the call centre where I was transferred from one Department to the next, to no avail. I then went onto the website and submitted an online enquiry requesting assistance, I received a reply,13/01/16 with a ref number: Ticker#:*** and no further correspondence. On Monday 18/01/16, I went to our local MTN Lifestyle Centre Tzaneen, I received a contract confirmation on 20/01/16, but till date have not yet received the 2 iPhone 6s handsets (these are popular products and should be readily available) as app**** for. I contacted them on 21/01/16 Calvin confirmed that handsets would be in stock that afternoon or early on 22/01/16. I contacted him again on 25/01/16 and he said they were now expecting the handsets that same day. I then went to the shop on 26/01/16, Calvin was off sick, another employee said they would only order the handsets today,26/01/16 but could not confirm delivery. I need these phones for business purposes, as being in the consumer supply industry, quality and service is number 1 priority. I find this service very dissatisfying.
