REFUNDING AS IT WAS PAID IN WRONG ACCOUNT

I don't have any problems with delivery as the guy at Pringle Bay is excellent. My problem lays with the admin, actually I want to say there is NO ADMIN. The Courier Guy has now 2 accounts, it first it was PUDO. When I go into Pudo I have to download Courier Guy. As with any new system one has to learn to work on it. I loaded the wrong account. I have send numerous e-mails and calls. The Head Office told me to send again my reason for refund as well as a bank confirmation letter. I did that, but received an e-mail, the confirmation letter is to old. The account was opened in 2012 and at buttom stated address of confirmation letter, they only see date of opening. That goes on for a while before they realised. Just now I received an e-mail from Herm**** (Overberg) stated that query was closed as I did not send information. OMW after at least 8 e-mails that were send - that for my own money.
