Repairs not done Very disappointed

Third time my phone was booked in for repairs in 4 months. Battery life is very short. I was told that the battery was replaced for the second time by the manager but there is no record of that and the Vodacom repair CALL centre says that it was NOT replaced though the manager said that I should take his word that it was. I've called 4 times today but the manager refuses to call me back or take My call. Battery lasting approx 5 hours with minimal use. Phone returned in poor condition . Manager promised replacement screen guaRd. I spent Money to update apps after first and second 'repairs' who will pay for that data now?
