********** debit transaction

I received a following message "please note that due to the festive holidays in December & January your subscription for your Matrix\Beame\Mix Telematics account reference *** will be deducted on the 20 December 2021. Your next debit order will be on the 1st of Feb 2022. For any queries or to make alternative arrangements please contact ***" Well i did call the number and I spoke to Linda and explained to her that i received and sms and i don't have a clue what this Mix Telematics is all about. she then transferred me to Lauwrence, who told me it's for my car tracker while i was busy explaining that i don't have any business with them, he told me to hold on. he put me on hold for almost 30mins and the phone was just ringing. all i wanted to know is where did they get my information and what car tracker are they talking about.
