Multiple excess fees charged for one claim

My Golden retriever visited the vet on the 29 October 2024 as she was experiencing hip discomfort and pain. The Vet prescribed a 2 month course of consistent pentosan injections to assist her hip discomfort and pain. Nala was required to take an injection a week for a month, which then became one every two weeks for a month.

So obviously, each injection was paid on each trip. I accumulated the invoices to submit one claim because it’s one course and surely should be part of one claim.

Medipet refunded but charged me an excess for each injection invoice.

For me this is unacceptable as it is one course over a period of time so surely all the injections should be treated as one claim with one excess payable.
