Awaiting for glasses for a month now

They came to our company on the 18 Feb 2023, debit order debited on the 25, I called to follow up they said they will be delivered by the 18th March to date nothing has been received, no communication at all from their side, I have made numerous calls to their client services no answer, they dont care abut their clients all they care about is the debit because there are quick to debit but 0% on client service. I guess they are going to debit my account again, may they please be aware I will want my full refund and cancellation should they debit my account without rendering the service this month, I cannot be paying for a service that was not rendered please
