Useless customer care and lying

My Sony Z3 compact came back damaged after a faulty camera lens was replaced after having the phone for less than three months. I get these vague replies here from vodacom apologizing for lack of communication and they assure me as soon as I have a job number they will get back to me.<br> <br> I have asked WHY and HOW the back cover on the phone which is ment to be water sealed can simply just start falling off. Secondly I want to know how this does not warrant a replacement of the device. Even the lady at the vodacom shop I showed my phone to agreed that it is un-acceptable and that the unit should be replaced.<br> <br> My job number is: ***5 and I get an sms to say it has been despatched back to Durban. Where I presume I should just shut up and go get it? Who cares about my un-answered queries? Especially after the people responding to complaints here on Vodacom's behalf seem to make false promises!? I have email proof saying they will escalate the matter once I have a job number and I hear nothing back, just automated sms's from the repair guys....thanks for nothing Vodacom.<br>
