Not impressed

Hi<br> I bought a iPhone 5c from mtn in Tableview 6 months ago. The phone was in a box and sealed. 3 weeks ago the charger didn't work and I got a new charger. The phone still didn't charge. I took the phone to mtn as its still under warrenty. Mtn tableview send me to mtn in motagu gardens. I then received a message later that day saying that it will cost me r3300. They also found rust inside the phone and pieces glued together. I NEVER opened the phone or took it in for repairs.I don't know where the rust and glue is coming from.The never fell into water ect. Im a big apple fan but not anymore. What should I do<br> <br> Regardt Bosman<br> [Email Removed]
