Refund not processed accordingly

Bankmed owes me a refund on my MSA. I called in a few days ago to update my banking details and the consultant sent a form to be completed and I did just that. The automated email advised that banking details would be updated in 2-3 days. I called in after 3 days and the consultant advised that it takes 5-7 days. During that duration I was told that my funds were about to be released but she will put it on hold until banking details be updated to avoid it being paid to the old account which was incorrect. This was a week ago.

I call in today to be told that banking details were updated and payment was done last week to the new details, meanwhile payment was done but to the old details.

I am very unhappy with the false feedback that was provided and would really like for my refund to be rectified and paid to the correct account.
