Handset Upgrade turns into nightmare!

Good day

I have upgraded my contract online in December 2021 and have received my latest invoice stating I have an additional contract on my name.

For some unknown reason the online upgrade was seen by the system as an additional contract !!!!! How must I pay this...its not my mistake ??

The lady at customer service told me that it happens regularly with online upgrades and the only way to rectify this issue is for Vodacom to collect my upgrade handset and then they will cancell the additional contract.

I am very confused why they cannot just rectify this in the backend as it is a known issue ??? I am already using the new device and the old one is broken...I cannot send it back ???

Please can a Manager from Vodacom contact me in order to resolve this in a proffesional manner.

Thank you
