Momentum Car Insurance

I'm so disappointed with service that i am getting from Momentum Car Insurance. Had a car accident on the 1st on January and up till today an assessment on my car has been. Their assessment process takes 3 - 7days but till today i haven't received any feedback. After reporting the issue on their facebook page their investigator called to tell he needs at least another 10 days . This is the second time receiving such bad service from momentum. In 2018 went through the same thing with the very same investigator. For them to speed up things i always have to complain first on their social media platforms
