NO PHONE. STILL PAYING!? USELESS CUSTOMER SERVICE!

I upgraded my contract on the 8th of December 2015 to an iPhone 6s Plus and when I tried to play music on my BRAND NEW phone, I realized that the earphone port wasn't working. The BRAND NEW phone ALSO stooped responding to Hey Siri.<br> <br> On the 11th I brought the phone back to the MTN at The Vaal Mall. I was told that even though I returned the phone within the 7 days they first had to send it in for warranty assessment before they replaced it.<br> <br> I asked the guy helping me if I needed to delete the apps I downloaded onto the phone and he said no. I insisted on deleting my banking app.<br> <br> When I came back on the 5th of January 2016, which was my 3RD time coming to check on my phone since their communication skills are POOR!! - they told me, only then, after I left my home and spent money on a taxi to get to the mall, that they couldn't asses the phone because I left the find my iphone app on, which meant they had to take the phone back again (something I doubt they ever did to begin with!?)<br> <br> I was told I can't get a new phone as they are still assessing (a process that is costing ME money)<br> <br> What I want is to cancel my contract and be reimbursed for the money I was charged!! I have NO phone
