Yoco non response, and failure to complete bank detail

A new card machine, was bought, paid for and delivered in good time. Good service indeed. Then the problem started. Pay out to our bank account is still impossible. My id document were send and accepted. Business details were accepted. Banking detail. I send 3 month statements, and a letter from the bank. This could still not be verified. They came back to me, requesting the original id of the person, opened the account. Unfortunately, the account were opened in 1998. And the original person opened the account, died in 2002. I am at this stage, the only signatory alive. Our next AGM will only be in Aug 2022. With that reason, we will have minutes of the meeting, to allow more signatories. After more attempts to get answers, it is totally impossible to get any answers. They refused to reply on my mail. Phone calls, is also impossible. I hope that this complaint, will set a better way of communication
