Poor Service, NO RESPONSE on claim queries

I generally brag about how good discovery is and being a fanatic ive moved all my services across to them, but unfortunately im really disappointed in the level of service im recieving from the medical claims department, both myself and my broker have tried to get a response out of them regarding medical claims that where logged numerous times but to no avail. Despite having a gap cover and + 200% hostpital coverage im still left with invoices to pay that should have been covered under the hospital admission. This is extremely frustrating as I stand a chance of my credit rating being damage due to negligence from someone else

Ive tried emailing the claims department numerous times with the same auto generated reply that someone will get back to me in 2-3 working days. guys I logged the last query AGAIN on the 21st July we over a month past. I cannot believe this level of service
