Horrible Customer Service

Absolutely the worst customer service I have ever dealt with.

I have been trying to change my bank details for months now. I emailed them with the 2018 form, in 2018. They respond, from an unattended email address that I need to send them my ID as well.

I reply - I hear NOTHING even though I waited for months.

Then I send them the forms again (Forgot the ID), then they respond and say they need a copy of my ID, and that they cannot accept the 2018 form. I need to complete and send the 2019 form. But they do not attach the 2019 form.

No I have to go search around online to try and find that form - NO LUCK.
