I have requested a copy of a VAT invoice for a purchase made by credit card. The supplier sent me a VAT invoice but charged VAT @ 20% on the gross value. I politely replied and advised them that the invoice was incorrect and asked that they send a modified invoice.
They sent me a modified invoice showing the correct net amount, but no VAT charged on the card processing fee.
I replied again advising the invoice was still incorrect. They told me that the invoice is correct because they do not charge VAT on the card processing fee (they are not a bank or card provider - they provide goods and the goods were paid by card via sagepay).
I asked again for a correct VAT invoice. I was sent an invoice which was completely different again and told that the goods were discounted and VAT charged on the full price.
I have now asked them to just confirm exactly which invoice they are using for their records so I can use the same for mine so the VAT is neutral at least. However, I am concerned that the company is a large company with UK turnover c£19m. Should I pursue this?
