Bad service with Discovery

I joined discovery on the 1ste of March 2023. If I received a account I had to phone in every time to sort out that account. I send accounts in to their claims dept my first one was on 11th of April and got feedback that they will process it 7-10 workings day today is the 2nd of May and still nothing was done. I only getting Sassa and it takes me every time 35min on the phone to sort out the accounts. I am very disappointed with discovery
