Poor communication

I was in an accident with my car on the 15/03/2021, after the accident I contacted my insurance for an insurance claim, they told me that they are going to pick up my car and everything went according to plan.

Now my car is at the repair shop but there is still no communication between my insurance and the repair shop, they are not responding to my emails nor picking up the phone and I've tried numerous times to contact them, they keep on sending SMS's that they will be in contact with me for more than a week now.

I have children that need to go to school, and also responsibilities that I need to attend to.

This is extremely frustrating as this is my first time claiming from the insurance.

I need this to be resolved as soon as possible as I cannot go another week without transport and also Easter weekend is upcoming and I would like to spend time with my family.
