Process after taking through a vehicle policy

Auto & General is a good insurer and overall its easy to deal with them. There have been many surprises with my recent vehicle that I have insured with them. They provide you tasks to complete, but their App doesn't update what you have done to the website and vise versa. Upon insuring my vehicle, I completed the tasks required from my end, providing proof of tracking for the vehicle and the vehicle inspection (tracking certificate provided twice, on the App and on my dashboard on line). I get an SMS message this morning saying my premium will be adjusted, because I have not provided proof of a tracking unit being installed in the vehicle. I call through, only to be told that I needed to have emailed the tracking certificate. For the life of me, I'm going through all communication and the policy documents and I cannot find where that is mentioned. Worst still, how was this added as a task for me to complete and upload, if the certificate needed to have been emailed? Overall good service, but this was just one annoying thing which they should have communicated better. Take off the option to upload the tracking certificate and just mention that the tracking certificate should be emailed. Now my premium will be adjusted for something I have completed. We will see.
