worst customer service

I had an accident in the beginning of December and I submitted my claim and had their external inspector come and investigate and ever since I have had nothing from them and I have to be the one running behind them, trying to figure out what's going on. They always say they will get back to me, but not once have they done that. Now they are not picking up their phone. I am very disappointed with this treatment. It has been has been 2 month going for the 3rd month with not a single response and update on my claim. How long are they willing to delay the process I wonder. When I phone I am being told this person is now handling my account then that person tells me that this account has been moved to someone else. I am just been given a run around.
