Midland Funds LLC review: Customer service

I called Midland Funds about an account I supposedly had with them. They said they can't find an account with my name or social security number in their systems. I asked for a letter stating this and they said they can't do that because I don't have an account with them. I asked to talk to the manager and they said that the manager is on the phone. I have been calling every day for three months.
