Vodacom staff shouts at their customers!

Vodacom are theives. My phone broke months ago and till today my phone is still broken. I have been to the repair shop 7 times and everytime they give me a broken phone back. It seams the use the part from broken insurance phones and put them together and sell them as new phones. I have the voice recordings where they promised me a new phone if I pay a R 400. They gave me my same phone back still broken. Achmat said weeks ago he will make sure I get my new phone them gave me a broken phone back. When I phoned to complaint he shouted at me. Utterly disguisting to treat customers like this and then run off with their money. Now I am sitting with a broken phone and Achmat's excuse was its because I used the camera. They did not tell me that I am not suppose to use the camera what type of ***** it this? Where is my money? How do you treat people like this and I have been returning to the store for months and everytime my phone is broken. This ridiculous!! Since when does Vodacom's staff when they have a bad day scream at their customers?? While they are helping you they talk and shout amongst each other about lunch chiprolls. Disguisting service!!! And everytime they tell when they dont know what say I must book the phone in but they keep giving me the phone back broken then shout at me when I am uspet! When you ask questions all they know what to answer is " Its out of our hands. " I HAVE BEEN BACK 7 TIMES !!!!!!!!! Rude and vulgar Vodacom terrible service and terrible people working for them!!
