Brand New phone doesn't work

I have been a customer with Vodacom for 4 days. I initially had to wait for a week for my phone to be in stock, (which I had to call find out myself) then had to wait for another three days for my number to port (was not warned about this) and then after turning it on for the first time I find my phone's battery does not hold a charge, it cannot download apps and when I eventually did download one the phone froze in a grey screen and would not respond to any input. As it was within 7 days I took it back for an OBF. There I was told I would have to go to a different vodacom as they were under renovation. I then got there and was faced with long ques. I returned to my initial vodacom where they could suddenly help me. They then couldn't tell me when I would be getting a new phone, if I would even get a new phone,and stated that I might hear back by Saturday but even then they are out of stock again. I have been trying to get a phone for three weeks now, have had to go into the store on three occasions, have received very poor customer service and I STILL DON'T HAVE A PHONE. Also I was advised to buy a R180 cover film which has now been handed in with the phone. I am totally shocked.
