Debit order date changes and NO feedback from Mixtelematics

"Dear Valued Customer, Please note our year-end billing schedule: We will bill your account on 17 December 2025. Your debit order will run on 19 December 2025.

1. Who gives you the right to one-sidedly change debit order dates? 2. I am a contractor and there will be NO money in my account on the 17th or 19th. 3. I asked via return mail that you honour the original debit order dates. This was done on the 9th. 4. I will NOT be paying for AODs due to your one -sided change of debit order dates. 5. ..and this is for an account where I've sold the vehicle. Yourself and Telcos are the only businesses I know of where you get penalised and have to pay for a service you will not get. This borders on ********ity.
