The worst customer service

Absolutely appalling customer service. The worst I have ever experience by a huge margin. I was involved in a car accident on 02 Jan 2022 and submitted my claim on 03 Jan 2022. I was told someone would get back to me within 48 hours and surprise surprise, that didn't happen. I ended up being the one to do a follow up and I was told my vehicle has been written off. Since then its been myself as the client constantly chasing them down trying to get an outcome of my claim. The past 3 weeks have been absolute torture dealing with this company, I can never get a straight answer, multiple empty promises of people telling me that they will get back to me, which they never do. I've been subjected to delay tactics and ***** business ethics. I just want to know the outcome of my claim THAT'S ALL. The amount of stress and anxiety I've had to endure because I don't know where I stand is unbearable. They were more than happy to take my premiums (very high premiums by the way), they were very quick to write off my vehicle but they can't seem to resolve my claim. Why is that?
