Incompetence at the very best

I took my phone in for repairs on the 06 December 2015, On the 14 December 2015, received an sms that the phone was ready, for collection at the Vodacom - Cresta shopping centre , Lo and behold on arrival the phone was doing the exact same thing , Is it not protocol for a phone to be tested after repairs, Obviously this was not done <br> <br> Now due to incompetence on vodacom side- How long do i need to wait for this matter to be resolved
