Worst service i have ever experienced

I am a 54 year old domestic worker and I feel I have been taken advantage of by Vodacom Musgrave, I have been without a phone since 31/01/2015. I lodged a cellphone claim with Vodacom which was approved by the insurer. i was told by Vodacom Musgrave that they would call me with details of my new phone. they failed to call me and I had no choice but to visit the branch. on the 11th of February I met a girl who gave me an attitude like i was asking her to pay the money from her own pocket. the girl told me again that she will call me and I have never received a call from them. on the 17th of February I called Vodacom as a private person, (i did not disclose my identity) to ask them if they had the phone i was looking for in stock they said \yes". when i got to the shop and they saw it was me they said the phone is no longer in stock. I have gotten my children involved in this matter. they told my son that they ordered the phone from Midrand on 24/02/2015 and when i called today 02/03/2015 they said they don't have stock. somebody please help. i run a baking business on the side and i am loosing customers!"""
