Disgusted!!!

I recently sent my phone to Vodacom for a software upgrade , on collection of my phone I noticed my screen (Samsung s6) has been damaged , I complain to the consultant who then says 'no problem' I will send it to the repair centre to fix... after waiting for 14days I receive an sms to say my phone is ready for collection, I drive 60km to collect my phone once again , and nothing at all was fixed/replaced ... the screen was still cracked .... now the consultant tells me they donot have screens in stock I should wait.... this is now 15days later I have not received a response .... my phone is still broken ... I am not able to continue with my business as my phone is my main tool .... Vodacom I want this screen replace in 24/48 hours or I want a new phone!!! or I will be taking this further and will claim loss off income!!!
