I have an interesting problem. Last September I had an accident in the Alps and incurred lots of medical bills for treatment/ambulances. I paid a few bills there and some invoices were sent to me after. All were paid by my insurers. However one of the Ambulances took my credit card details but never charged me. I sent their paperwork with the rest to my insurers. I assume it had all been settled and could forget about it.
Today I find that Ambulance crew have charged an amount to my card, a full 5 months after! Any further bills served on me after coming how were sent to me via normal mail and forwarded to my insurance company. They all had my insurers contact details and policy number. I have raised a payment dispute with my credit card issuers as I don't think this is acceptable. It will prove hard to claim from my insurers without a proper invoice and I see this is the only way to ensure I get proper paperwork.
Any comments?
