UPGRADE DUE - NO RESPONSE - GETTING TIRED OF COMPLAINING

Dear Vodacom I am still waiting for an upgraded phone. Nobody gets back to me. The wrong phone was delivered and collected on 14 October 2017, thereafter nothing! Not a phone call to say madam we will amend your Order. Nothing! I have been sending emails to a specific person, without any response. Upgrade was due in May 2017 and still no luck! It feels obvious to myself that Vodacom could not care less about their clients. Keeping nobody happy, not responding, not giving the correct deals as discussed. Some feedback or response will be much appreciated.
