Device fee *2 in one month

Took an upgrade with Telkom using *123# 24th December 2019, upgrade done successfully phone delivered on the 31st December 2019.

Received my Jan 2020 I am charged a device fee for 2 devices for December 2019, this is a device i used less 24 hours since i received. Call customer service 3 times all 3 consultants had 3 different explanations to why my bill is high for January 2020.

My request is simple either reverse the R949 device fee for December 2019, or since i am within the 7 days cooling period cancel the contract and come fetch your device. i will continue with a different network.
