Quality on service & repairs

I've been without a phone since 27 September 2015. Now that it came back from the Advanced Repair Centre, it still has problems. This is a brand new handset I got on 1 August 2015!! <br> The level of service from Tygervalley up to the Advanced Centre in JHB has been one big joke. First I can't get a loan phone from Tygervalley, but they want to sms me on the progress of the repairs. Hello!!! You just told me you don't have a loan phone for me. After that I never got any quote for repairs to be done, but I have to approve the quote for them to go ahead. Even gave my email address for them to email it to *** I have is my the piece of paper with the job number on I got at Tygervalley. So I have been calling since Thursday last week to find out exactly what is wrong with it. By Monday I had enough and requested the Advanced Repair Centre's number. After a struggle I eventually got some sort of answer. Now that the phone is back in Cape Town today it still gives problems. Why does it leave the Advanced Repair Centre in the first place without being tested properly? At the point to cancel my contract with Vodacom completely.
