Terrible service and *********** staff once again

My Sony Xperia Z3 has been sent in for repairs. Firstly I was told that the phone is not a VSP phone and won't be repaired thereafter being told that it will be investigated. This has been 2 months without having my phone. My phone is still under waeranty and I pay for insurance. I have to use my own airtime to phone and ask what is happening and all they say is that they will find out and never get back to me. To this day I have no idea where my phone is or what they are doing to solve the problem. This is not the first time I have had a problem with Vodacom and I need a replacement phone or repaired phone as I am without a phone that I am paying for. I won't be renewing my contract with Vodacom. I hope this issue gets solved fairly and punctually. This is ridiculous.
