FAULTY DEVICES

I took my phone in to the Truworths in Eastgate Mall, on the 2nd December. When I called the MTN follow up centre on ********** 564 was took that the phone was only taken to the centre on the 7th meaning that the process was now delayed. I was promised weekly updates but none where provided. Everything I called the store I was told that the Cellphone lady is on lunch and I will be called back but now call back was provided. I am highly disappointed with the service that I have received. This is the second time that I have purchased a phone from the store and they end up being faulty. Why does MTN provide Truworths with faulty devices. I now have to pay the monthly instalment for a device that I do not have in my possession. Meaning that I need to purchase another device to have Truworths then returning the ****ty Nokia N7plus back. this is incredibly unfair. I request rapid feedback and a proper phone.
