Bad service

My phone cracked scrrenn and I took it to Vodacom repair centre at Fourways mall. I took it in on the 18 August 2015 and only got it back on the 22 October. On receiving it i found out that the front camera is not working. I took it back on the 23th October. Towards the end of November they called me to ask for the passcode, I get them the passcode and was told it is not working, which was impossible because I have 1 passcode for everything.It was only on the !st December that I was told thant e fixed and I will get a new phone. I am still waitung.
