Very BAD Service

I went to MTN Woodlands on 6/09/15 to upgrade my fiance's phone which is on my name. I also asked them to put another contract (iPhone 6 64GB) also on my name for myself. The lady told me that they need to approve the new contract & MTN HQ will let me know via sms. 07/09/15 at 16h00 I received the sms from HQ. After work I went back to MTN Woodlands to collect my iPhone 6 64GB & as the lady scanned the phone she told me that my credit limit was to low & she will request for it to be increased. I was NOT informed about the increase on 06/0915 as they new what we wanted. The lady said the HQ will let me know once my limit has been increased and it can take 48 hours. 09/09/15 I had not heard anything as yet & decided to go back as it had been 48 hours. The man who helped me said it has not yet been increased so I said just give me the iPhone 6 16GB which I can take without the credit increase. As he scanned the phone it threw out an error on their system. He said they will fix the error on 10/09/15, deliver my phone on 11/09/15 & I asked him to keep ME UPDATED. No phone was delivered & no one phoned me. I phoned on 11/09/15 & was told error had not been fixed yet. UNPROFESSIONAL!!!!!
