SAMSUNG S4 MINI

I have a contract with Vodacom and with the renewal of it i took the Samsung S4 mini end of last year. This phone is such a problem because the battery heats up even if the phone is not being used. I took it to Vodacom and they sent it away for repairs. The phone i got back but there was no difference. I then went into Vangate to complain that the phone heats up but they say that is what the Samsung phones do. About 3 weeks ago the phone just switched off and did not go on again. I went to Vangate branch again and they told me to go to KC or Canal Walk to have the upgrade done. SO i went to KC which is closer for me and there they tell me they cannot do it i have to pay, i must go to Canal Walk. How frustrating. I went to Canal Walk and there they kept the phone and i waited for 3 days. Got the phone back and they replaced the mother board. Ever since then my phone is freezing, getting hot still, switches off while im busy with it. I dont even have the phone long and it went in for repairs twice. I went to Vangate again and they say i must go to Canal Walk. I hate this phone and i pay every month.<br> S.Khan
