No customer service. they can't even do paperwork!

I was a nashua mobile client for many years. Then they forclosed and sent me to MTN! I upgraded my contract to a data package and laptop in March 2015, Fabian Jordaan (sales consultant) handled the upgrade, he was supposed to cancel insurance on the phones and insure the laptop and assured me that's what he did. My laptop got ****** and I wanted to claim only to find out it's not insured!!! I went back and He doesn't work there any more. Store manager R.Heuvel took the matter. She now had to request the paperwork, unbelievable! A month later and still nothing. Now 4 months later I am still strugeling with mtn they don't phone back nor respond when you are in store! Insurer said the store has to take responsibility for this because it was their employees that are at fault!
