Job number ***5 ( Samsung S5 for repairs)

I have a Samsung S5 contract phone of which I took it in on the 16th July 2015 for repairs in Vodacom Shop Golden Acre, Cape Town because the screen was not displaying (operating system hanging). I have been making a follow up since then, all they can tell me is that they awaiting for spares of which they do not know when would that arrive. I am without a phone for 20 days and I use that phone for business.
