December 2018 book in for repairs 2/2/2019 still no Phone Vodacom you suck!

I have a Vodacom Contract Early last year 2018, I recieved an upgrade on my Cellphone but decided to continue using my existing phone. Towards the end of 2018 my Iphone needed repair and during those few days I unboxed and used the New Huewei P10 Lite until the return of my trusty Iphone. Early in December 2018 I needed the phone once more at this point the phone would not start up even a good over night charge did not help. I then handed the phone in at Hillcrest Vodacom for repairs and was informed it would only be ready early January 2019 due to all the "Public Holidays" accepting this as valid enough reason, I left it at that. To date I still do not have my phone Vodacom's T&C's talk about 21 day TAT! Where is my phone and if it's not repairable where is my replacement Phone! Vodacom come to the party here sort out my phone under warrenty or simply replace it!
