Billed for what exactly

Bought a new vehicle from Renault which comes with tracking device and this was in December 2020. I was told by the Renault retailer that it is included. Since December, I have been billed separately by Netstar. I called to find out why it’s like this, the lady Portia asked me to email the prove I have as confirmation because it does appear on their systems that they have been billing me. This was on the 23/06/21. I called again on the 02/07/21 and was told I would receive a call before EOD. It is the 05/07/21 and have not received any confirmation email or even the reference which was supposed to be sent on the 23/06/21 till today.
