Unprocessed payments

I recently (7th of January 2020) made a purchase in Holland using my Capitec bank account (i am living in Holland until March 2020. I have sent an email to Capitec for help regarding 2 unprocessed payments. One of them has gone through already and yet another payment has been deducted for the exact same purchase, resulting in me paying a double price for this one purchase. As I am overseas Capitec doesn’t contact me even though I updated my contact details. Please see to it that this is resolved as I can’t reach capitec. 2 unprocessed payments resolving in over a thousand rand. Thanks
