Bad repair service

I gave my Sony Z3 compact in for a screen repair. Vodacom Menlyn repair centre sent it away for repairs. <br> <br> This was done on Monday the 4th of May 2015 and a received the Estimate via email for the screen repair on the 18th of May 2015 @ 14:00. The Estimate was already made out on the 7th of May. I have phoned them about 7 times between the dates 11th of May and 20th of May but they don't answer. On two occasions they answered but put me on hold and never responded. They were of NO assistance. The morning of the 20th they told me via SMS they won't repair my phone because I don't respond. A day and a half is BARELY enough lead time for me to respond as I am a very busy person. <br> <br> When I phoned to ratify this problem ASAP in the morning of the 20th of May when I received the SMS, they answered finally and told me they will book it in again. I have been trying to phone them since, but they don't answer or put me on hold again. This is very frustrating as I need my phone to operate my daily life! It has been 7 and a half weeks since I gave in my phone for repairs. This is absurdly bad service that I am receiving. I will be moving from service provider.<br> <br> Job# ***8
