Refunds not processed per preferred method after several requests

Ordered a specific item, as ordered just more than a year ago, as it needed to work on the same app (security camera). Wrong product delivered, returned the items, as the call centre said it was just a product labeling issue the correct product should be delivered on the next try. When order received, using the credit on my account, AGAIN the wrong product. So I returned it and REQUESTED A REFUND, not a credit on my account. BUT my request resulted in a credit is adjusted to my account not the REFUND as I requested. Then the excuses started. So I called them again... no sure we will refund the credit on your account. Almost 5 working days later no refund - it still sits as a credit on my account. Take a lot now also don't have a GENERAL enquires contact number anymore - you can only call about delivery and returns. You call the ONLY available number, they transfer you as YOU now I HAVE TO PROVIDE THEM WITH YOUR BANK DETAILS, which i refuse to do (***** and identity theft is at epic proportions everywhere)... so they cut you off, don't provide the details where they are transferring you and don't bother to contact you...
