Trust Broken

I took my phone to Vodacom repair centre at Menlyn on 16 Feb. my screen was giving me issues. the phone was booked in the same day. I then got a call on Thursday 18 Feb from Vodacom insurance saying that the screen needs to be replaced & excess would be R900. I agreed to pay. On 20 Feb I got a message stating my phone was ready for collection. I fetched it on 21 Feb. same day after my screen & LCD had been replaced by phone gave me the exact same issues. Took it back on 22/02/2016 and again my phone was booked in. This time I was told that my phone needed a software update and that it would take 12 - 25 hours. I waited 25 hours & then called Menlyn to enquire when my phone would be ready & I was told it has been sent to the advanced centre.Nobody bothered to tell me and I had to call in to find out what was going on. on the 24 Feb I received a message stating my phone has been sent to the advanced repair centre. I called repair centre on 29 feb to find out when my phone would be ready & was told it had not even been assigned to a technician. It was assigned the next day.today is 4 March & still no phone. almost 3 weeks later. trust with Vodacom is gone and i will be moving to MTN
