Total lack of customer service

I upgraded to the Z3 at the end of last year. In January I dropped my phone, and the screen shattered. Fully aware that I would have to pay for repairs, I sent my phone back to Sony for repairs through MTN. When the quote for over R6000 came for the screen (that's 60% of the cost of a brand new phone, for 1 part), I thought there must be a mistake and raised a query on 31 Jan 2015 to gain clarity as to why the cost is so exorbitant - I thought the quote had to be incorrect. <br> <br> I got a response on 2 Feb asking for all my details in order for a Sony representative to follow up on my case. I promptly provided the required details.<br> <br> Since I supp**** all the information (3 Feb 2015) I have still not received any feedback, and I don't have my phone back yet either. Its been a 6 month wait so far. I wonder If I will ever be able to use my expensive Z3 that I am paying MTN for every month before it is time for my next upgrade.
