What is going on with Vodacom

The service delivery I've received from Vodashop Jabulani and Vodafone is just appalling. I took my iPhone for repairs to the service center in Jabulani mall on the 31/10/2015 and it's now a month later and I still haven't received my phone I've heard excuse over excuse. I have been to the outlet over 3 times and on all three occasions I've heard different stories,from the phone is still in Midrand,to Find my iPhone was on and the could not be fixed and I had to over 5 times spoke to a Itumelang that I gave my iCloud details so they could switch off this find my iPhone from there side and I got a email confirmation that it was deactivated this was around the 15/11 and I called the outlet again on the 20/11 and was told again find my iPhone was on and spoke to Itumelang again and stated it was still on and we would deactivate it again. I call again to day 25 days later and I get told the phone is in the shop and hasn't been even fixed. What do I need to do get some service . I spoke a Onkametse who confirmed that the phone is still in the shop
