Totally Disappointed

i ported 3 cell c contracts to mtn corporate accounts with candice (excellent service) and received our handsets via courier on 18 April 2015. this morning my samsung galaxy s6 was off for no reason (fully charged) and would not switch on. i went to rustenburg waterfall mall in the morning and was informed by a white young lady with blonde hair that I need to bring the phones chrager and proof of corporate account contract before she can assist. i went all the way home and back again and stood in the queue to be assisted for over an hour - the lady that assisted earlier was not in the store. when i got to the front and was assisted by lesego she informed me that she could not help me at that store with this account and I needed to go to the other mtn store in the mall. i was livid that i was not told this the first time by the white young lady. when I went to the other store there was a slow moving queue of roughly 10 people and i just very despondently turned around and left knowing I was not going to be assisted today as it was already after 2 pm. i cannot be without my phone and the nano sim does not fit in any other handset i have as these take micro sims. my phone is 2 months
