Europ Assitance does not pay the Service Providers

I am Towing Service Provider been assisting Europ Assistance since 2018 August and 90% of my invoices have not been paid by this Company. I assisted many of their clients in Cape Town and in the rural in Transkei, Eastern Cape but payment does not come through. They keep on asking for invoices to be redone and they always say we used wrong ratings.

Their ratings are worst. They have not paid our invoices since last year and I have sent numerous emails. This company is ****ing the Towing service providers.

They are contracted with the insurance companies and they get paid for the towing that we do and they don't pay us the people, who actually did the job. When they said my invoices were incorrect I asked them to pay the correct amount according to them, but till today my invoices have not been paid.
