POOR / NO SERVICE

I purchased a new LG G3 phone and after 3 months it broke. I took it in for MTN to check it out & the lady said the phone damaged and needed to be warranty replaced. She passed it on to another guy who check it, dropped it by accident and clipped everything back together and suggested I bring the original box & fitting the next day. On the 31Jan 2015 I took it back to the MTN THE GLEN and when the lady checked the phone again, said the phone is damaged & because the screen is cracked. Warranty will not apply in this case however it will be sent in for repairs. I complained because only the day before they agreed it was ok for warranty, then their staff member dropped the phone & now I have to pay for repair cost. I told them to check it in and quote me for repairs. I was told that by 4th Feb I should get a quote and within 2-3 weeks the phone would be back at store. Well I never heard from them at all and I finally traced my phone which only arrived at the repair centre 1 week later. 2 weeks later they phoned for a quote after phoning everyone to find out what the problems is. Its now the 9 March & still haven't heard anything or got my phone back. MTN SERVICE SUCKS!
