Not poor service, but NO service

I work for a medical bureau, we submit claims to the medical and follow up for payment. Sizwe Hosmed is one of the worst medical aids to call when it comes to claim queries. The consultants try to be helpful but are unable to do anything except send emails. Team leaders or managers are never available to sort out a problem (always in a meeting or on another call) and the claims department simply has no interest in sorting out a problem. Claims for 2023 has still not been paid and the only info you get is, we will escalate for processing. Complaints have been submitted but the only reply we received is to inform us that A more substantive response to your problem and a suitable solution will be provided to you within 3-5 business days. Not sure how long a day is in the world of Sizwe, but I'm still waiting for a solution or a call.

If anyone from Sizwe Hosmed can actually contact me, that would be great.
