Phone not fixed after multiple repairs

<p>I have sent my phone in for repairs twice over the last few months. Each time it came back worse than before. This time there is a bubble on my screen that was jot there before it was sent in for repairs. Each time i have to be without my phone for 2-3 weeks I lose business because i depend on my phone for business. The first time I took the phone in because it overheated, switched off and would not turn on again. It came back with something loose inside and the speaker phone not working in addition to the overheating. It then started turning off randomly and would not switch back on. Still overheating and the battery only lasting about 3 hours at a time. I sent it for repairs again and it has come back still overheating to the point that it was too hot to even touch. This is in addition the the bubble on the screen that was not there before it went in for repairs. I need a more permanent solution from Vodacom because I am basically paying for a contract and the phone has been in for repairs more than I have had use of it. </p>
