Extremely poor product and service - fleet cameras

I had cameras installed in 5 of our company vehicles. Initially the cameras worked for approximately 1 year, then the cameras stopped working. Unfortunately support within their company is non existent. I have had four changes to account managers and still have no response from the last contact.

I have requested the company to resolve the camera issues and stop debiting our account. Despite numerous attempts the issue has not been resolved but my account is debited every month.

I have asked to have this escalated but still no access to management or feedback. Lastly I have now tried to cancel the contracts, also not actioned as per the request.
