Refund Duplicate payment

So FNB refuses to refuse a duplicate payment because Wesbank is internal.

Wesbank can clearly see they have been paid twice and I need the debt order reversed, the other payment was a cash payment and I do not have the proof of payment or slip.

You guys now say you can't refund me.

This is ridiculous.

I am having so many problems with FNB and Wesbank, if this is not resolved by the end of the day I am done. I am moving over to Nedbank and MFC as they made my life to easy when my finance was with them.

This is your last chance Wesbank and FNB. I am not accepting any excuses or justfications. Reverse my debt order. You can't use the fact that you are linked to FNB only when it suits you.

Please communicate with me via email.
