My complaint towards Vodacom

Hi my name is Noma I would like to share my experience with Vodacom and how I have been treated recently, here is my story on December 22nd 2020 I bought a phone that is 2,4 Nokia on credit and I pay installment monthly as I supposed to also I was informed that if the divice is giving me problem within 7days I should bring it back to the store and they will give me a new one but that is not the case here because the device was working perfectly for about 3 months on march 20th it started giving me problem of not reading the sim card I even tried putting other sim card just to figure out what was the problem so eventually I noticed that the problem was the device so I took it back to Vodacom The Glen that is where I bought the device and the date was 31 march 2021 so and the consultant advice me that if I desperately need my device I should take it to the repairs myself of which I did hiring an Uber to Alberton Voda repairs and on the 14 April 2021 I collected the phone also I had to hire an uber as I do not have a transport of my own so I was happy for a little while until it stops reading sim card again and now it was April soon after repairs and on month end April I took it to the shop now for the second time, so again they booked the device in, so all this time they refusing to exchange the device even for a different model that would have been better instead of this in & out booking for repairs and this time it was already 20th June the day I went to collect the device and that was not the last time because even now the device is not reading sim card again I took it to the shop which is today 10th July and this time I pleaded with the manager to exchange the device and he refused and told me to book it in now for the third time with the same faulty problem so I just snap and left the shop with my toy phone and now I desperately need your advice on this matter.
