Bad service

On the 7th September I took my phone into Vodacom for repairs ,my screen cracked and they said it will take 2/3 days to fix which i was fine with ,on the 9th of September i got an sms to say my claim was put through for 4800 which I had to phone myself to approve .I then called into Vodacom a week later to find out what was happening since I didn't get any feedback and then the agent over the phone said my phone was ready to collected ,with no notification at all from Vodacom. On the 17th of September i collected my phone from the Vodacom fourways only for the guy to come with my phone and half of the tapping was still coming out as well as my whole back cover was still loose on the phone which is not right and I asked him how does a well known company like Vodacom give you such disgusting work on one's phone when I'm paying almost 250 for insurance only and I get a phone that is not even fixed ...The manger of The repairs then came up and took the phone back to the hardware to fix the issue .I left the branch with my phone only to get home and notice that even now my speaker is messed up as well ,I then took the phone again on the 3 October to Vodacom the lady and guy who assisted me said that my phone will take 2/3 working days .Here I am a week later and still no call or sms from Vodacom on what's happening. O tried complaining via email directly to them on the 17th but since then no response what so ever .I'm extremely disappoint in the bad service that I've recived from Vodacom.
