Double debit orders for the month!!!

I have a loan account with Capitec, and their monthly debit order went off on 26th of the month correctly but today on the 28th October again they debited my account, customer care was unhelpful and asked me to go to the branch with my bank account statement proving the amount was debited only to get to the branch early on in the morning to be told they are aware of the issue and a number of people were affected with debits to other banks, no estimated time of resolution available or any other info available, we are just supposed to wait until they decide to sort out their systems whilst we make a plan on how we are going to get by whilst they are holding on to our money and trying to figure out how they missed this up. Please sort out your bank and refund my account, and have the decency to update customers affected by your incompetence.
