Extremely poor service vodacom

My Samsung s4 had been booked in for not charging on 20/7/2015. About 1 week prior to booking it in I assumed it was the battery and purchased a new one but still no luck. On the 20 July vodacom repairs messages to say phone is ready, report stated electrical parts replaced. The problem persisted and phone got rebooked on 31 July for intermittent chArging and was sent back on 4 August with report stating 1 part wS changed and client to check the charger. Phone got rebooked on 5 august. At this point I requested a new phone and I was told an assessment needs to be done at a higher level to consider this. Phone was sent to advanced repair centre on 6 August and received there on 11 august. Phone was assessed and went for quality check on 12 august. Was despatched to umhlanga on 13 august. Went to collect phone on 14 August and as per report no fault was found. The manager was called in and assured me he would personally check the phone and call back the next day. Off course that did not happen and I called in on 17 August and was told by the manager that he will call me back to confirm what is going on during the day. Off course that too dint happen. Frustration point reached.
