Unsatisfied customer

Terrible service. Vodacom contacted me to upgrade my data package to include a tablet. I agreed to same and proceeded with the upgrade. I never received my package despite getting a call from the driver of the courier company to arrange a delivery date, and changing addresses on the whatsapp platform, not one call received from Vodacom or the courier company and today I have been informed that the transaction has been cancelled??? No one can tell me whether the entire upgrade is cancelled or whether I'm expected to pay more now without the tablet???? Terrible communication.
