Bad service to the core

On the 3rd of April I emailed Momentum Short term insurance to update my daytime parking and only to receive the below email and even today I'm still waiting. Worse today I got an accident and have captured my claim online then no1 calls me, I called them twice to hold on for 30 min because the call center is busy. Now I have to drive a damaged car with the location not updated. if 15 days passes they will reject my claim due to day time parking.
