Complaint on Car Insurance Claim

It's more than a month now my car hasn't been fixed. It was reported and there is claim number. I have been making follow-up for several times. It has been traumatizing, frustrating, confusing, caused enxiety and shocking the level of customer service Hollard is providing to clients. It is definitely can't be caused by COVID-19 pandemic as many would claim. It's just that Hollard Insurance doesn't have what is called " A Culture of Customer Centricity Approach and Systems in place. Please help me to follow up on them.
