Mandate Unsuccessful Nightmares'.

Mandate nightmare, filled in all the information as required, the same as all the previous years, and all of a sudden the mandate was unsuccessful. Followed the instructions to correct it, but I still can't transfer it and can't resubmit the mandate. Tried reaching out to them, but no response, no assistance. I can't transfer my funds, and I need to pay bills. Very unprofessional service.
