RCS Refunds

I have overpaid on my Edgars account and have been back and forth since August 2020 for a refund, all consultants I have spoken to can see the credit due to me when viewing my account but none are able to action after all information requested have been provided on numerous occasions. In December 2020 I finally got forwarded to RCS 1st Level complaints where I dealt with Randy. A number of emails have been sent to date with the same information requested: proof of payment, copy of ID, banking details, which have been supp****, no response has been received nor have I received the refund. Calling doesn't help either as I am transferred from one department/person to another that's if the calls are not dropped in my ear.
