Bad service

<p>I have a contract with Mtn, later my iPhone 6 gave me problems freezing and switches it self off. I took it back to MTN Store in Ermelo because it was still under warranty, they told me to check it after 3 weeks. After 3 weeks they said the Repair Centre didn't fix it because the application Find My iPhone was not deactivated, they said I must pay an amount of R330 so that the repair centre will took it back. I paid that amount and I deactivated find my iPhone online, they are apologies about not telling me to deactivate that app the time I gave them the phone. But still the repair centre send it back after I paid that amount, they promised me to sort it out that problem. After a month when I went to check it again they told me another story that the repair centre said they are not going to fix my phone because it was out of warranty. But the time I gave them my phone was still under warranty, my phone stayed with them for 5 months but they didn't not fix it. They time I gave them my phone it was working but now it is not working at all, I don't know what they did in my phone. I so disappointed by Mtn I still paying for that phone but they don't want to help me now.</p>
