No communication from MixTelematics

In 2020 I sold my Kuga and asked to cancel the tracking system and put a new system into my new vehicle. Up until today the amount for the Kuga is still being deducted. Only noticing this recently I sent a mail to them and got this reply I got on 02/09/2022. Kindly note your reference number for the query: ***2. Should there be any outstanding information this will be communicated to you via email or phone. Another email sent on 27/09/2022 - ***8 & ***9 - got these two reference numbers but no replay. So, the debit order for the new month went off still charging me for the car I don't have for over 2 years now. I tried phoning them this morning holding on for over 40 min, I tried all the different options available, but no one is answering. Hopefully someone will see this and come back to me!
