Zero customer service

I am at my wits end. 5 days later and absolutely no response from Whitney at Discovery Insure. Not even an email to say they're working on it, and I've sent multiple emails requesting feedback. I also phoned yesterday and spoke to Kayleigh who said she'll get Whitney to phone me back, but did Whitney? Nope! Nothing! My car needs repairs and the report was sent to Discovery on Monday for approval already, it's now Friday and absolutely NO WORD from Whitney or anyone at Discovery Insure. And the report clearly states that further damage can happen if the car is driven like this. Is Discovery Insure going to pay for the additional damages too because they're the ones who caused delay? I highly doubt it. I have NEVER witnessed such bad customer service like this.
