The worst service I've ever experienced

Four weeks ago to the day (24/06/15) my phone was sent to the Vodacom repair centre in Bloemfontein for a cracked screen. Two weeks later (08/07/15) the phone came back with the screen barely attached to the phone itself. It was loose in 3 of the four corners. So much so that I could actually see inside the phone. The next day (09/07/15) the phone was sent back to bloemfontein. Today (22/07/15) I went to pick up my phone only to find out that they did not do ANYTHING. The phone was sent back with a note saying \no defect found". It will be sent back to bloemfontein today and probably take another two weeks before its back in who knows what condition. So for 6 weeks I'm without a cellphone which is having a sever impact in my job. I make about 300 calls per day. My company has 10 R2000 pm contracts and this is the service i get. I demand an explanation and to have my phone back in working condition by Saturday or a new phone. Job number: ***2"""
