How was this issue sorted for you guys? Its been over 10 weeks since my VAT started appearing as invalid. Despite several calls to HMRC, nothing has been done. We always get standard response from them that the case has been forwarded to VAT team, and there is nothing further they can do. This is really frustrating, annoying and highly unprofessional. All my VAT payments are up-to-date, however, VAT checker shows me as invalid.
