Vodacom Repairs dissatisfaction

I took my phone in for repairs on the 23rd of July , job no ***3. The sms stated it take 2-3 w/ds however the ladies at the booking desk did advise it may take up to 7 days. Which i was fine with, i called the repairs call centre on 2 occasions thereafter at which point i was advised they are waiting for parts. I received an sms on Friday the 7th of August and proceeded to pick it up on the 8th, at which point i put my sim card in the phone and was still unable to access network, they tried to see why this was still happening and asked that i leave it and they will send it to head office, a few days later i was advised the device was blacklisted hence i could access network , i filled in forms to remove it from blacklist and was advised to switch it on 2 days later . which i did only to find it is still not working . Went back in the 24th of August and booked it in again with Job no***8 and discovered that it was not fixed the 1st time around ( as per system notes ) and that i came to fetch before it could be fixed. ( which is not true) still no phone and no feedback , i have been without my main device for over a month. The ladies who booked it in are very helpful however it seems the issue lies with the people who actually do repairs. If they cant really fix it they must come up with a feasible way forward, i have been more than patient.
