Struggling with claim payouts

I was involved in an accident early in may, before i lost consciousness i dailed the emergency in app number logging in all my details and no response, i got admitted ini a government hospital receiving the worse possible service, i continuously phoned and phoned after multiple attempts a consultant eventually takes my call and explains to me that they cannot do interhospital transfers as i was requesting to be moved to a facility where i could get better treatment but all my efforts were in vain. After i got discharged a couple of days later i was waiting on the doctors to fill in my claims and it was at that point clientele continuously phoned and pestered me the more i explained that I'm still waiting, they then understood and told me to send the hospital bill which was the only proof i had at the time,i did as they demanded and onky to find days later that they say the documents are insufficient and my claim wil be closed until i send them the needed documents. 3months after the accident the hospital phones saying that my paperwork was done and i had to pay them apon collection(which i did) i then sent the documents thru to clientele who assures me that they will stay in contact with me to keep me uo to date with what's going on, and to this day i haven't received no word from them and whenever i phone them they are more and more surprised when i ask about my claim and then promising to phone me back and they never do, in the meantime they are harassing my girlfriend asking her if i pay my premium regularly. Please shed light on the matter because the way i feel i want to take my business elsewhere, you promise people the world but when push comes to shove you fail your clients
