Capitec won't return my unprocessed amount

I am extremely disappointed by the level of service from Capitec, I keep purchasing from Woolworths and they like every other delivery service puts through an initial amount and then only deducts and changes the amount after delivery. I have to keep contacting Capitec to reflect the unprocessed amount back into my account, the response I got today from Unathi Somdaka was just ridiculous. I was told to get the merchant to dispute the amount or get them to process the amount so the Card Disputes Department can assist me. Please can someone from Capitec that knows what they doing contact me about Incident# ***7.
