Samsung J1 repair

must say i am completely dissatidfied with Vodacom and Samsung at the moment. i purchased a Samsung J1 smartphone cash a few months ago.<br> <br> <br> This phone has now started giving problems such as, freezing, the phone gets hot and shuts itself down, when opening applications it hangs for hours or it just closes it.<br> <br> <br> i Booked the phone in for repairs with the Vodacare in Vincent East London, they replaced the main board on the phone. collected it, used it for a week and it still did the same thing. i took it back in for the Second time and they replaced the battery. i collected it again and once again the same thing. this is now the 3rd time i have taken the phone in for repairs. they now tell me that the phone is going to be dispatched back to the repair centre in east london and they have done a software update.<br> <br> <br> im sorry but i canot accept this. i cannot keep going back and forth booking in this phone. i have a business to run.<br> I have sent numerous emails to vodacom to try and get this resolved as I am not happy, I have had no luck. I received an sms to say that the phone is really for collection, sorry but I'm not collecting. I want a new phone.<br> <br> <br>
