An sms was received about my fault cat track unit dated 13April'20. It was noted that I should book to have it repaired. This is a public holiday yet the unit/chip used for tracking is critical in an unsafe really where cars are constantly being ******. This also directly impacting car insurance claims which are dependent of having a working tracking system. I called the number *** yet after a minute and half with no voice prompts or some indication that this line is attended to it was aborted.
