Pathetic service

I had gone to vodacom 4u at the Pavillion about 3 weeks back. Did a business application for an iphone 6s plus that had a problem with experian credit check they had incorrectly added some stuff which I fully understand. The problem was resolved later about a week later. The staff member attitude stinks its like I am working for her. Whenever you call the store the staff are busy or the person has stepped out. When u ask to speak to the manager there is no manager. However I was called to come into the store last week cause the phone was ready only to be told 40mins after waiting there is no stock. In disappointment I leave and was told if I find another vodacom that has the phone to inform them and they will do a dealer swap. I had found it ,contacted the Pavillion branch via the other vodacom store to find out that the staff had stepped out and will contact me,and only she can do my deal cause she does business accounts and no one else can assist me and yet again there was no manager. Its gone yet another day and no feedback or joy . Please help
