have samsung s7 and cant use it

<p>i upgraded on my contract on 7 feb2017 to a samsung s7 phone. 2 days later the phone started to freeze and i had to reset it 4-5 times per day. the phone was VERY warm when i used it. i was in JHB and did not want to give it in there as i stay in Knysna. 7 days after the upgrade the phone froze every few minutes. on 8 March i broke the screen and had to send it for repairs. this phone is used for bussiness and i do not know how many calls i missed when the phone froze. i handed the phone in at Knysna Vodacom on 8 March 2017. i received the phone back on 4 April and realised the phone did not work properly. i send it back for repairs on 5 April. the phone is still not repaired. this is realy not acceptable and i would like to receive my phone now, repaired or replaced. i pay for something i do not have to use.</p>
