Over 2 weeks and still waiting for phone etc

On 15/10/2015 we went to apply for a New Contract with Ngutho at Irene Mall. On 17/10/2015 we took the last documentation required. Authentication was done & all was ok. The week after, I phoned on 20/10/2015 to confirm if all is in order & no one knew what was going on. Then we went in the following day & spoke to Aron. He helped & said he would try to get it sorted asap as it was still with credit vetting but that it should've been done already. Then I phone the day after & get told no one knows again & then again that it is with credit vetting. I eventually spoke to Trinity who confirmed that she will do everything she can to help. Head Office said they would source a Samsung Galaxy S6 Smartplan 100 R399 p/m, which I was then told that Head Office said on Wednesday 28/10/2015 that they will be sending a phone from Fourways and should be there that day or on Thursday. Nothing. No feedback. I am sick and tired of having to phone to hear what's going on. There is no feedback/follow up calls. I phoned today 30/10 & was told that it is still with credit vetting. What nonsense is this???? I want this sorted out ASAP! Over 2 weeks!!! This is unacceptable and unprofessional!
