Billing issue with Indirect Provider

I completely understand, however usually with other software or hardware vendors there is someone that is working with the Distributors on the partner behalf and/or CSP indirect provider to help when the Distro/CSP indirect provider is not providing the product or there is an issue. I have gone through the CSP providers helpdesk/ticketing and not getting any satisfactory help. Just in summary - ordered 3 Annual pre-paid licenses in March for a tenant and applied correctly to the tenant. July 5th the licenses disappeared from tenant. Open ticket with CSP with no response, Applied trial license so that tenant could use their MS365 in the meantime. CSP cancelled subscription saying it was a problem with Microsoft. No refund for the 8 months left on the 3 pre-paid annual licenses. 21 days later CSP support told me to purchase 3 new licenses as it was a Microsoft issue. So now my client had to purchase 3 new licenses. I know this cannot be correct and how can we as Microsoft partners for almost 25 years get help. The CSP is saying it is Microsoft fault and Microsoft is telling me to work with the CSP provider that is not providing the licenses that were paid for. We did buy the 3 new licenses on the tenants behalf just a few days ago so our tenant can continue to conduct business. Is there anyone that can assist in working with both the partner (us) and the Distro/CSP to get this resolved.
