Fed up with Hosmed not paying bills

I'm in complaint process nr 4 you know what you just get ignored. 17 years with hosmed had no issues then came covid and down the drain goes good Service. You know what you blindsided everyone with the Value Core option promised nothing will change except for the Life and Netcare providers and covid came and suddenly you have new rules and loopholes and blindsided the client. I'm fed up for sending email after email complaining about bills from doctors not getting paid you have an excuse for every thing just to not pay the bill. If you have done your work properly and gave us the full details as of Universal taking over as administrator but instead we get errors on our bills. Not paid not paid really. Everyone in the call centre off Universal is giving us different stories every single time we call. Now suddenly our GP that we have been using for 17 years is not set on our primary GP list. And account not paid. I really can go on and on
