MTN disappointed me!

I app**** for a cellphone contract over the phone with MTN, was assisted by Noleen Naidoo.I only used the phone for 2 weeks then all of a sudden the device just went off ,I tried to charge it but still that didn't work.work . I took it to Southgate to have it checked ,the lady that was helping confirmed that the phone is faulty and that she will have to take it back FINE!She gave me a reference number so that I can do a follow up which I did. I called the contact centre spoke to a lady who could help me ,she said she can't open the attached document that's linked to my profile.profile . I asked her if her supervisor can't view the attachment and she said NO they can't. I later called Southgate spoke to a guy called Kgosi and he confirmed that the courier company came to collect the device and also mentioned that it's a process that will take about 3 months. So that means it's 3month without a phone!! FINE!!I asked him to cancel the contra and he told me that I need to pay a certain fee,I asked him how much should I pay and he said he will give me a number that I can call to find out.out . He gave me this number ********** 667..Guess what!! That number belongs to multichoice..How unprofessional and *********** is that!! I'm so mad because no one is helping me and I need that phone for my business. No on is saying anything,I get transferred all over!no one is helping me!!
