I would like to complain about my dissatisfaction with the service received from Vodacom, I upgraded in Nov 2014 and took a Z3 Blackberry however the phone had a software problem and within 3 days gave the phone back a requested for a different Phone a Hawei which I was pleased with, just to find out in March 2015 that I am being changed for 2 hand sets and not receiving any statement until I picked up the error as to why I am being debited so much I expect a full refund as I am being charged incorrectly for a phone I don't have I do not want a credit on the account and I am wrongfully being debited incorrectly.<br> <br> Today around 12.00am a receive a call for a consultant from vodacom world to advise my phone Z3 is ready for collection I do not have a Z3 and expect a refund. or will be cancelling my debit order and taking this matter further.<br> <br> Contact urgently as I expect feedback on this as I am tired of this mess up.
