Vodacom collections not happening

Vodacom, please stop claiming you are the best SA network as you can't even complete a simple task such as collecting an unwanted phone. My husband upgraded his contract to a higher package on 7 August 2020 and was given a new contract instead. The new device was delivered very quickly after which the mistake was picked up and the contract after sales department was contacted. They promised to rectify the mistake and to arrange collection of the device. A month later the device has still not been collected, and they had the cheek to debit his account at the end of August as well! We have phoned Vodacom 3 times over the course of the month and every time they have a different story and promise to arrange collection, yet nothing happens. Seriously Vodacom, how difficult can this be? If the problem is with your courier company of choice, maybe it is time to reconsider.
