Phone has been repired 4 times in 3 months

I am not satisfied with service received from Vodacom these past months.<br> <br> It seems every time I take my phone in for repairs it does not get fixed. I have taken my phone in 4 times for the same problem and the 4th time booking my cellphone in, Vodacom repair sent the phone to the advance center - but problem still persist. I was informed the motherboard of my phone has been replaced and its new but it still has the same problem. I haven't had a proper functioning phone from September and its January now.<br> <br> I sent Vodacom escalations an email and According to Divan from Vodacom \This is the 1st time that the device has been booked in according to the system."i gave him all of my references and still he told me that the same phone that cannot be repaired is at Fourways repairs and i should test it Again. I am not a tester i want a working device i cannot keep taking that device in every month for the same problem that should have been repaired. <br> <br> Vodacom is not doing right by me.i have been paying for a phone that i do not have for closed to 5 months now.
