Unprofessional

I have been holding on the line for the payment and billing department the whole day. I’ve been transferred to them 4 times but no one is picking up and the internal sales department says there are agents available but no one is answering. My account has been suspended but I’ve been approving the debit order. I can’t process the payment online because there’s a pop of an error that keeps coming up. So unprofessional. Please assign someone to me ASAP
