Bad administration for queries/ claims

I have two outstanding queries that have yet to be resolved with Profmed regarding non-payment of claims due to "incorrect tarriff codes". I have been backwards and forwards with the suppliers/ providers to get this sorted out, but the code is the code. The response from Profmed, if you can get hold of them, is "we've escalated this to the appropriate department". The one query dates to May 2025 - still no resolution. The other dates back to August 2025 - still no resolution. The administration from Profmed is shocking. If you get hold of the agent, it's always the same thing, we'll escalate - who are you escalating this to?

I have been with Profmed since university days, and for the first time have started looking at other options for 2026 - I cannot handle this shocking admin anymore.
