Upgrades and Retentions

I've been a Vodacom customer for over 25 years. Sick and tired of their pathetic customer service. Did an upgrade via retentions on the 31st March 2022 with a S22 handset and galaxy watch 4. Consultant checked the system and said they have stock of both devices and they will be delivered to me within 3-4 working days. After my 1st call to them to query where is my devices, the consultant says theres no stock. Now my package get cancelled without even authorisation from my side. I have been calling everyday to sort this out but their workers are completely *********** and everyone has a different story. I have requested for them to pull the recorded call up, asked to speak to manager but everytime I get told the manager will call me back, but still no call for the past 10 days. Shame on your pathetic service after been a VIP customer all along.
