Constant delays in getting a claim processed

I've been trying to get a valid claim processed for 3 weeks. I've sent through the required documents 3 times. Every time I call a consultant tells me I must send it again. Discovery does not respond to my email questions or requests for feedback. When I send through the required documents I just get told to \wait 3 days until they process the email\", whatever that means. After 3 days nothing happens, so I call again - same story. "
